ImgFormats

Convert, compress, and resize images entirely in your browser — no uploads, no sign-up, no watermarks. Supports JPG, PNG, WEBP, AVIF, HEIC, GIF, and BMP with instant bulk processing.

imgformats is a browser-based toolkit to convert, compress, and resize images — with no file uploads, no sign-up, and no watermarks.

How it works

Every tool runs entirely inside your browser using client-side JavaScript. When you drop or select an image, it's processed directly on your device — nothing is ever sent to a server, stored, or seen by anyone else.

Tools included

Image Converter — switch between JPG, PNG, WEBP, AVIF, HEIC/HEIF, GIF, and BMP
Image Compressor — reduce file size with an adjustable quality slider
Image Resizer — resize to exact dimensions or common presets

Why it's different

Most online image tools require uploading your file to a remote server, which means waiting on upload/download times and trusting a third party with your images — even temporarily. imgformats skips that step entirely, so conversion is instant and private by design.

Common use cases

Converting iPhone HEIC photos to JPG for compatibility with Windows and messaging apps
Compressing a photo to meet a file-size limit for a job application or form
Resizing images to exact dimensions for social media, passport, or ID requirements
Converting images to WEBP or AVIF for faster website loading

No accounts, no daily limits, and no software to install — just open the tool and use it.

Questions & Answers

As answered by people managing ImgFormats.

What makes ImgFormats unique?
imgformats stands out because of how conversion happens — entirely inside your browser, with no server upload at any point.
- Your images never leave your device
- No account, sign-up, or watermark
- No daily limits on how many files you can process
- Bulk processing with one-click ZIP download
Most competing tools require uploading your file to a remote server, which means waiting on upload/download times and trusting a third party with your images. imgformats removes that step entirely.
Why should a person choose ImgFormats over its competitors?
Most image tools — like CloudConvert or TinyPNG — process your files on a remote server. That means an upload wait, a download wait, and your image sitting on someone else's infrastructure, even briefly.

imgformats processes everything locally, in your browser, so:
- Conversion is instant — no upload/download delay
- Your images are private by design, not by policy
- There's no account required and no artificial usage limits
If privacy and speed matter more than server-side "extra" features, imgformats is built for that.
How would you describe the primary audience of ImgFormats?
imgformats is built for anyone who needs a quick, one-off image fix without installing software or trusting a third-party server:
- People converting iPhone HEIC photos to JPG for compatibility
- Job seekers compressing a photo to meet a file-size limit on application forms
- Web developers and content creators optimizing images (JPG/PNG to WEBP/AVIF) for faster page loads
- Anyone resizing a photo for social media, passport, or ID requirements
It's designed for both non-technical users who just need something to work, and developers who appreciate that no data is being transmitted anywhere.
What's the story behind ImgFormats?

imgformats started from a simple frustration: needing to quickly convert or compress an image, and every available tool wanting to upload the file to some random server first.

That felt unnecessary for something modern browsers can already do natively — decode, transform, and re-encode an image using nothing but client-side JavaScript. So imgformats was built to do exactly that: handle conversion, compression, and resizing entirely on-device, with nothing sent anywhere.

It's an ongoing, actively maintained project, with new tools and format support added based on real user needs.
Which are the primary technologies used for building ImgFormats?
- JavaScript (Canvas API) for client-side image conversion and resizing
- heic2any for HEIC/HEIF decoding in-browser
- JSZip for bulk ZIP downloads
- WordPress with Elementor for the site and content layer
- Google Analytics and Google Search Console for site performance insights
