Resize an image

Set the width and height a form asks for, or scale the whole image down by a percentage. The original dimensions and the result are shown side by side so there is no guesswork.

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

How to resize an image

  1. Choose your image. Its current dimensions appear immediately.
  2. Enter a width, a height, or both — or switch to percentage scaling.
  3. Leave "lock aspect ratio" on unless the form demands exact dimensions that do not match your photo’s shape.
  4. Choose the output format, then resize and download.

Supported formats

JPG / JPEG, PNG and WebP, in and out.

Important limitations

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

  • Enlarging an image cannot add detail that was never captured. A 200-pixel photo scaled to 800 pixels is just a blurrier 200-pixel photo, so upscaling is off by default.
  • With the aspect ratio locked and both a width and height given, the result fits inside those bounds rather than filling them exactly. Unlock the ratio to force exact dimensions — the image will be stretched.

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 result is not the exact size I typed.

With the aspect ratio locked, one side is calculated from the other to avoid distortion. If the form insists on exact dimensions, either unlock the ratio and accept the stretch, or crop the photo to the right shape first with the passport photo tool.

My image looks squashed.

The aspect ratio is unlocked. Turn it back on and resize again from the original file.

How do I convert centimetres to pixels?

Multiply by the DPI and divide by 2.54. At the 300 DPI used for printing, a 3.5 × 4.5 cm passport photo is 413 × 531 pixels. The passport photo tool does this conversion for you.

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.
Does resizing reduce the file size?
Yes, and usually far more than lowering quality does. File size scales roughly with pixel count, so halving both the width and height cuts the data to about a quarter.
Will resizing blur my image?
Large reductions are done in stages rather than in one jump, which keeps text and thin lines sharp. Fine detail is still lost on any big reduction — that is unavoidable, since there are fewer pixels to hold it.
