How we make this list: we compare pricing pages, product documentation and public user reviews. Ratings come from G2, Capterra or Trustpilot, with the date we checked them.
Key takeaways
- Catbox stands out for simple file URLs up to 200 MB with no account required, so alternatives must match that simplicity.
- Imgur, Postimages, and ImgBB give the closest free, no-account image hosting with direct links for forums and posts.
- Cloudinary suits developers and businesses that need image transformation and a global content delivery network.
- Flickr suits photographers who want a portfolio and community alongside hosting, with 1,000 free photos.
- Free hosting is public by default: anyone with the link can view the file, so never upload private or sensitive material.

The best Catbox alternatives
Starting priceFree
Free planYes
Imgur is the most familiar free image host, and its direct links work across forums, chat, and posts. An account gives uploads that do not expire, plus captions and email upload, while the platform supports PNG, GIF, APNG, and TIFF images plus video formats. Non-animated files up to 50 MB and animated files up to 200 MB are supported, with uploads capped at 50 images per hour and no lifetime limit on an account.
The limits matter. Imgur's terms restrict using it as a website image library or content delivery network, and images uploaded without an account have been deleted in the past, so an account is now effectively required for lasting links. Since September 2025, Imgur has also blocked visitors from UK IP addresses, so a link shared with UK readers may not load. Imgur fits best for casual sharing to a broad audience outside the UK, with an account for permanence.
What we like- Huge, familiar platform
- Direct links for forums and posts
- Account uploads do not expire
Watch out for- Terms restrict using Imgur as a website image library or CDN
- Anonymous uploads may be deleted
- UK visitors blocked since 2025

Free planYes
Postimages is the closest no-account alternative to Catbox for forum and website images. Uploads produce permanent direct links plus forum and website hotlink formats, with a free limit of 32 MB per image and support for large dimensions. No account is needed to start, which matches Catbox's simplicity for a quick share.
The trade is resolution and control. Free hotlinks are shown as limited to 1280 pixels, so full-resolution sharing needs another route, and no account means less control over managing or deleting uploads later. Postimages fits best for forum posts and quick shares where a permanent direct link matters more than full resolution or account management.
What we like- No account required
- Permanent direct links
- Forum and website hotlink formats
Watch out for- Free hotlinks are limited to 1280 pixels
- No account means less control over uploads
- Smaller feature set
Starting priceFree
Free planYes
ImgBB is the simplest uploader in this list. Its homepage uploader accepts images up to 32 MB on the free tier, returns direct links plus prepared HTML and BBCode embed codes, and lets users set an expiration date for an image. No account is required for a quick upload, which suits a one-off share to a forum or a chat thread.
The limits are ads on the free service and management: account and plan details affect how uploads can be managed later, and there is no advanced editing. ImgBB fits best for quick, simple image shares where embed codes matter and a full account is unnecessary.
What we like- Very simple uploader
- Direct links plus HTML and BBCode
- 32 MB free uploads
Watch out for- Free plan has ads
- Account features affect management
- No advanced editing
#4Cloudinary
Best for: Developer image hosting and CDN4.4/5 on

Starting priceFree
Free planYes
Cloudinary is the professional pick for teams that host images as part of a website or app. Its free tier includes 25 GB of monthly credits, with global multi-CDN delivery, on-the-fly transformation for resizing and format conversion, and an API for automated uploads. For a business that serves images to many visitors, that infrastructure beats a free consumer host on speed, reliability, and control.
The trade is setup. Cloudinary needs developer time to integrate, and its free tier has API limits that a high-traffic site can exceed. A casual user sharing one image will find Imgur or Postimages simpler. Cloudinary fits best for developers, businesses, and content sites that need reliable, fast image delivery at scale.
What we like- Global multi-CDN delivery
- Image transformation on the fly
- Generous free credits
Watch out for- Needs developer setup
- Free tier has API limits
- Overkill for a single image share
#5Flickr
Best for: Photographer portfolios4.1/5 on
G2 (332 reviews, checked Oct 2026)
Visit flickr.com
Starting priceFree
Free planYes
Flickr suits photographers who want hosting plus a portfolio and a community. The free plan includes 1,000 photos, with embed links and albums for sharing work on a website or a portfolio page. Its community of photographers gives feedback and discovery that a bare file host cannot, and its organization tools suit a growing body of work.
The limits are account and purpose. An account is required, and Flickr is built for photography, not for quick anonymous file shares or hotlinking to forums at scale. Flickr fits best for photographers who want their images seen, discussed, and organized, rather than for a one-off direct link.
What we like- 1,000 free photos
- Strong photographer community
- Embed links and albums
Watch out for- Account required
- 200 MB per photo limit on free
- Less suited to quick anonymous shares
Starting priceFree
Free planYes
Imgbox offers unlimited free storage with permanent direct links and no account required for basic use, which makes it a strong Catbox alternative for small images. Its simplicity suits forum posts and quick shares, and its direct links work without extra steps. For a user sharing screenshots, memes, or small photos, Imgbox covers the need at no cost.
The limit is file size: 10 MB per image, far below Catbox's 200 MB. Large photos, high-resolution art, and videos need another host. Imgbox fits best for small-image sharing where unlimited storage and permanent links matter more than large file support.
What we like- Unlimited free storage
- Permanent direct links
- No account required for basic use
Watch out for- 10 MB per image limit
- Plainer interface
- Fewer features than Imgur or Cloudinary
Starting price$3.99 per month
Free planFree trial
ImageShack is a long-running image host with full direct linking and built-in resizing tools, which suit users who share images at controlled sizes. Uploads up to 25 MB are supported, and its tools cover cropping and resizing without a separate editor. The paid plan at $3.99 per month gives full access after a 30-day free period.
The trade is that full use requires payment, unlike the free-first tools in this list, and its community is smaller than Imgur's. ImageShack fits best for users who want direct linking plus resizing in one paid tool and do not need a large social audience.
What we like- Full direct linking
- Built-in resizing tools
- 25 MB uploads
Watch out for- Paid plan required for full use
- 30-day free period only
- Smaller community than Imgur
Starting priceFree
Free planYes
ImgLink is the closest Catbox-style alternative for direct image and short video links. Uploads need no account, with PNG, JPG, WebP, GIF, and SVG images plus MP4, WebM, and MOV videos supported. Guest uploads allow 25 MB per file and up to five files at a time, while signed-in uploads allow 50 MB and up to 15 files, with direct URL, HTML, Markdown, and BBCode outputs.
The limits are size and privacy. Link-only sharing is not password protection, so anyone with the link can view the file, and the service is newer than Imgur or Postimages, so its long-term track record is shorter. ImgLink fits best for Catbox users who want the same no-account direct-link workflow for images and short clips.
What we like- No account required for uploads
- Direct links plus embed codes
- Images and short videos
Watch out for- 25 MB guest limit, 50 MB signed-in
- Link-only sharing, not password protection
- Newer service
How we chose
We compared these tools on direct-link support, file size limits, account requirements, permanence, and whether they suit casual sharing or professional delivery. Figures come from vendor pages and current comparison guides checked in October 2026, and any figure we could not confirm is marked as See website. We did not claim hands-on testing. Instead we weighed public documentation, terms pages, and user reviews, plus the practical difference between a consumer host and a developer CDN.
What to check before you pick
Start with the file. A screenshot under 10 MB fits almost any host here, while a 200 MB video needs Catbox-style limits or a proper file transfer tool, not a consumer image host. Next, check permanence: anonymous uploads on some services expire or get deleted, while account uploads on Imgur and Flickr last longer. Finally, check the link format you need, since forums, websites, and chat apps each prefer a different embed style.
Privacy, permanence, and hotlinking
Free hosting is public by default. Anyone with the link can view the file, and search engines may index public uploads, so never upload private, sensitive, or copyrighted material you do not own. Hotlinking rules also vary: Imgur restricts CDN-style use, Catbox requires approval for commercial hotlinking, and Postimages limits free hotlink resolution. For a business website, use a proper CDN such as Cloudinary rather than a consumer host.
When to use a file transfer tool instead
Image hosts suit public sharing, not private delivery. For sending a large file to one person, use a file transfer service with expiry and password options rather than a public image host. For a website's images, use a CDN or your own hosting, since consumer hosts can change terms, delete uploads, or block regions without warning.
Frequently asked questions
What is Catbox used for?
Catbox is a free file and image host that gives simple direct URLs for uploads up to 200 MB, with no account required. It is popular for sharing images, GIFs, and files in forums, chat, and posts where a direct link matters more than a social feed.
Which Catbox alternative needs no account?
Postimages, ImgBB, Imgbox, and ImgLink all allow uploads without an account. Postimages and ImgLink give the closest Catbox-style direct links, while ImgBB adds embed codes for forums and websites.
Can I hotlink images from these hosts on my website?
It depends on the host and the use. Postimages and Imgbox support hotlinking, while Imgur restricts CDN-style use and Catbox requires approval for commercial hotlinking. For a business website, use Cloudinary or your own hosting instead.
Do free image hosts delete uploads?
Some do. Imgur has deleted images uploaded without an account, and guest uploads on some services expire. Use an account and keep a local copy of any image you cannot afford to lose.
What is the largest file I can upload free?
Catbox allows up to 200 MB, which beats every free tool in this list. Among alternatives, ImgBB and Postimages allow 32 MB, ImgLink allows 25 MB for guests, and Imgbox allows 10 MB per image.
Is Imgur available in the UK?
Since September 2025, Imgur has blocked visitors connecting from UK IP addresses, in response to Online Safety Act scrutiny. A link shared with UK readers may show as unavailable in their region, so UK audiences should use Postimages, ImgBB, or another host.
