About Easy Image Converter

Last updated 8 September 2026

Why this exists

Converting an image online has traditionally meant uploading it to a stranger's server. Your photograph is copied to a machine you know nothing about, processed there, and — according to a line in the footer — deleted at some later point. There is no way to verify that, and the files people convert are frequently the ones they should be most careful with: passport photographs, signatures, medical letters, pictures of their children.

That upload was never necessary for the work itself. It was necessary because browsers could not decode and encode images on their own. They can now. Every current browser ships complete image codecs, and WebAssembly covers the remaining formats — HEIC, AVIF, TIFF, JPEG XL — at close to native speed.

Easy Image Converter is built on that. Nothing is uploaded, because nothing needs to be.

How it works

When you drop a file in, the page decodes it using either your browser's built-in image support or a WebAssembly decoder downloaded on demand, resamples it if you asked for a resize, and re-encodes it in the format you chose. All of that happens in the tab you are looking at. The finished file is handed to your browser's download mechanism directly from memory.

Because there is no server doing work, there are no queues, no file size caps, no daily limits and no reason to charge you. It also means the site keeps working offline: load a page, turn off your network, and convert away.

What is here

• 101 format conversions, each with its own page explaining what is preserved and what is not
• Compression to an exact file size, using a search for the best quality that fits
• Resizing to standard dimensions, including passport and visa photo sizes
• Plain-English guides to the formats themselves

How it is paid for

Hosting a static site costs very little, which is the point of doing the work on your device. Costs are covered by advertising, which is kept out of the way of the tools and never disguised as a download button. There is no premium tier, no account and no upsell.

Accuracy and corrections

The technical claims on this site are meant to be correct, including the unflattering ones — where a format is bad at something, it says so. If you find an error, please write tofuturetekapps@gmail.com and it will be fixed.
