Fifty kilobytes is one of the most common upload limits on the web. Passport renewal sites, national ID and driving licence portals, scholarship applications and online exam registrations frequently ask for a photo "not more than 50 KB". A photo straight from a phone is often 3 MB or more, roughly sixty times too big.
This compressor is set to 50 KB. It keeps as much quality as possible by searching for the ideal JPG setting, and only reduces the pixel size if it really has to. Faces stay natural and documents stay readable. Since the tool runs entirely in your browser, your passport photo and personal documents are not transferred anywhere.
How to use the Compress Image to 50KB tool
- Take or choose a photo with a plain light background, as most ID portals require.
- Drop it onto the box. The target is already set to 50 KB.
- If the portal gives pixel dimensions, enter them as the maximum width and height.
- Check that the final size is under 50 KB and the face looks clear.
- Download the JPG and upload it to the portal.

Passport and ID photos at 50 KB
At 50 KB a head-and-shoulders photo of about 600 × 600 px keeps excellent detail, which is why many portals choose this limit. If your form asks for a square photo, crop it to 1:1 first with the Crop Image tool so the face is centred, then compress it here.
Requirements vary by country and service: some ask for a minimum size as well (for example 20–50 KB), a specific pixel size, or a white background. Read the official instructions, and keep your original photo in case you need a different version later.
Compressing document scans to 50 KB
Scans of certificates, ID cards and mark sheets often need to be under 50 KB too. Crop off the table or desk around the document, and scan in good, even light: a clean white page compresses far better than a gray, shadowed one. A full A4 page can become hard to read at 50 KB, so if text gets fuzzy, check whether the portal accepts a PDF instead.
Frequently asked questions
How do I reduce a passport photo to 50 KB?
Drop the photo on this page. The tool automatically finds the best JPG quality under 50 KB and, if necessary, reduces the pixel size. Then download the result.
My portal says 20 KB to 50 KB. Will this work?
Yes. The result is just under 50 KB, comfortably inside that range. If you need a smaller file, use the 20 KB preset or type your own target.
Can I compress several documents to 50 KB at once?
Yes. Add all your files together; each one is compressed to under 50 KB separately, and you can download them as a ZIP.
Does the photo quality drop a lot?
Not for typical ID photos. A 600 px portrait fits in 50 KB at a high quality, so the face stays sharp and natural.
