Compress an image

Make a photo smaller without guessing. Move the quality slider, compare the result against the original, and download only when you are happy with it. If you need to hit a specific number of kilobytes instead, use the compress-to-KB tool.

Your file stays on your device. This tool runs entirely in your browser — nothing is uploaded to our servers, and nothing is stored.

JPG, PNG or WebP · up to 50 MB

How to compress an image

  1. Choose a photo, or drag one onto the upload area.
  2. Move the quality slider. The preview and the new file size update as you go.
  3. Optionally cap the width or height — on large phone photos this usually saves more than quality alone.
  4. Check the preview at full size to make sure the detail you care about survived.
  5. Download the compressed image.

Supported formats

JPG / JPEG, PNG and WebP images up to 50 MB. Output is JPG, PNG or WebP, whichever you choose.

Important limitations

Worth knowing before you start, so nothing here comes as a surprise at the point you are submitting a form:

  • Compressing an already-compressed JPG a second time loses more detail each time. Always start from the original file where you can.
  • PNG output ignores the quality slider. PNG is lossless, so the only way to shrink it is to reduce the dimensions — or switch the output to JPG.
  • Very large images (roughly above 50 megapixels) are rejected, because decoding them reliably crashes browsers on low-memory phones.

How your files are handled

This tool does its work using your browser’s own image and document engine. Your file is read from your device into the page’s memory, processed there, and offered back to you as a download. It is never sent to Fyleit, never written to a server, and never stored anywhere we can reach.

You can verify that for yourself: load this page, disconnect from the internet, and the tool still works. That is also why there is no sign-up and no email field — we have nothing to attach an account to.

Common problems

The file barely got smaller.

That usually means the image was already well compressed. The next lever is dimensions: a 4000-pixel-wide photo displayed in a 600-pixel box carries about forty times more data than it needs. Set a maximum width and the size will drop sharply.

The compressed file is bigger than the original.

This happens when you convert a simple graphic, screenshot or line drawing to JPG. Those images compress far better as PNG. Switch the output format to PNG and compare.

Nothing happens when I select a file.

Check the file really is a JPG, PNG or WebP — a file renamed to .jpg is still rejected, because the tool reads the actual contents rather than trusting the name. Files saved from some apps as HEIC also need converting first.

Frequently asked questions

Are my photos uploaded to a server?
No. This tool uses your browser’s own image engine, so the photo is read, processed and saved entirely on your device. Nothing is sent to us, and nothing is stored. You can confirm this by opening your browser’s network tab, or by disconnecting from the internet after the page has loaded — the tool keeps working.
Why does the image look slightly different after compressing?
JPG compression works by discarding detail the eye is least likely to notice. Small reductions are invisible; large ones show up first as soft edges and blotchy patches around text and in smooth areas like sky or skin. If you can see the difference and you do not like it, raise the quality or allow a slightly larger file.
What quality setting should I use?
For photographs, 70–80% is the usual sweet spot: a large size saving with no difference most people can see. Below about 50% the artefacts become visible, especially around text. For an application form where only the file size matters, go lower.
Does compressing remove EXIF data like location?
Yes. The image is redrawn from its pixels, so camera metadata including GPS coordinates is not carried into the output. Orientation is applied first, so the photo will not come out rotated.
