About Image Compressor
Image Compressor is a free suite of browser-based image tools: compressing photos to an exact file size, resizing to exact dimensions, converting between formats, handling animated GIFs, and reading or removing the metadata hidden inside a photo. It exists because those jobs are common, genuinely useful, and far more awkward than they should be.
Privacy by design
Many tools never upload anything at all. Where a file does reach our server it is held in memory, used for the one operation you asked for, and discarded when the response is sent.
Real image engines
Compression and conversion run on libvips, the same library behind many professional pipelines, with ImageMagick covering the unusual formats.
Free, with no account
No sign-up, no watermark, no daily cap and no paid tier holding back the useful settings. Running costs are covered by advertising.
Why this site exists
Almost everyone runs into the same wall eventually. A job application will not accept a photograph over 200 KB. A government exam portal wants a signature scan at exactly 140 × 60 pixels. A website is slow because its hero image is 4 MB. An email bounces because the attachment is too large.
The existing answers are worse than the problem. Desktop editors want an installation and often a subscription for what amounts to one export dialog. Many free websites bury the tool under advertising, cap the file size until you pay, or stamp a watermark on the result. This site is the version we wanted: state the outcome you need, get the file, leave.
How it actually works
Where a job can be done in your browser, it is. Resizing, cropping, rotating, most format conversions, and both metadata tools run entirely on your device using WebAssembly and the browser's own image support. Nothing is uploaded, and they keep working if your connection drops after the page has loaded.
Some jobs genuinely cannot be done that way. Hitting an exact target file size takes repeated encoding passes and a quality search that browsers are too slow at. Animated GIFs have to be decoded frame by frame and rebuilt, which browsers cannot do at all. PDF conversion and the less common formats — HEIC, TIFF, AVIF, PSD — need proper image libraries. Those run on our server, built on libvips with ImageMagick behind it for the awkward cases.
When a file does travel to the server it goes over HTTPS, stays in memory for the few seconds the work takes, and is discarded when the response is sent. It is never written to disk, never logged, and never used for anything but the operation you asked for. Each tool page states which of the two paths it uses, and the privacy policy covers it in detail.
What we try to get right
Target sizes, not guesswork. You enter the file size a form demands and the compressor works backwards to reach it, instead of leaving you to nudge a quality slider and re-check.
No silent damage. Animated GIFs keep every frame and their original timing. Metadata removal rewrites the file container rather than re-encoding the picture, so no quality is lost. Transparency survives. Portrait photos do not come back sideways.
Honest about limits. Some things are not possible — HEIC cannot be written without patent-encumbered encoders, and metadata cannot be stripped from HEIC or TIFF without re-encoding. Where that is the case the tool says so instead of quietly producing something worse.
Who runs it
Image Compressor is an independent project run by a small team of developers, not a company with a sales department. There is no venture funding behind it and no plan to introduce a paid tier for the features that matter. Hosting and processing costs are covered by the advertising shown on the site, which is why the tools can stay free and unlimited. If something is broken or a format you need is missing, telling us is genuinely the fastest way to get it fixed — get in touch.
Available in 19 languages
The site is translated into Spanish, Portuguese, French, Italian, German, Dutch, Polish, Swedish, Russian, Turkish, Arabic, Japanese, Korean, Chinese, Vietnamese, Thai, Indonesian and Filipino alongside English. Translation coverage is still growing: every language has a home page and the most-used tools, and the language menu tells you when a particular page is English-only rather than sending you somewhere unexpected.

Everything is free and needs no account. The compressor is the most used starting point, but the full set is on the home page.
