How do I compress an ID photo to exactly 100 KB?

Drop the photo in and the target is already set to 100 KB. The tool lowers quality, and reduces dimensions if needed, until the file sits at or below 100 KB. If small text or a face looks soft afterwards, crop tighter so more of the budget goes to the part that matters.

Is it safe to compress my passport or ID here?

Yes. Unlike converters that upload your file to a remote server, this processes everything locally in your browser, so your identification documents never leave your computer. Closing the tab leaves nothing behind.

The form wants a specific size in pixels as well — what do I do?

Crop to those pixel dimensions before compressing. The 100 KB target handles the byte limit; the pixel size is a separate rule the form checks on its own, so you need to satisfy both.

Will compression make my document text unreadable?

Not if you keep the resolution up. Text survives lower quality far better than downscaling, so for a document-heavy scan let quality drop toward 100 KB rather than shrinking the page. For a photo, crop close and the face stays clear.

Can I compress more than one document at a time?

Yes. Add several files and each is compressed to 100 KB on its own, then handed back, so a photo, an ID scan and a signature for the same application are ready together. Nothing is uploaded between them, and no account is needed.

Job portals, visa applications and government forms often cap a passport photo or ID scan at 100 KB, and reject anything heavier. This tool brings the file to that size in your browser, so the upload goes through — and because nothing is sent to a server, your ID never leaves your device.

Why so many official forms stop at 100 KB

A 100 KB cap is the standard on portals that collect one photo or document from huge numbers of people: recruitment sites, university admissions, visa and passport services, tax and banking forms. Storing millions of applicant images adds up fast, so each upload is held small to keep the system affordable and quick to back up.

The instructions usually pair the byte limit with a required format and pixel size — a JPEG passport photo at a set resolution is the common case — and the form checks all of them at once, rejecting the submission if any one is off.

Compressing an ID without losing legibility

What matters on an official document is that a face stays recognisable and small text stays readable, not that colours are perfect. Crop the image to the frame the form wants first — head and shoulders for a photo, the document edges for a scan — so the 100 KB budget is spent on the important part rather than the background.

Then let the tool lower quality until the file clears 100 KB. Photos of a person hold up well at the modest resolutions these forms use; a dense page of small print is tighter, so keep its resolution up and let quality carry the compression, since text tolerates that better than being scaled down.

Your passport and ID stay private

These files are as sensitive as documents get, which is the strongest reason to keep them off other people’s servers. Every step here runs locally in your browser: the image is read from your disk, resized and re-encoded in memory, and handed straight back for download. It is never uploaded, cached or logged anywhere, so a passport page or a bank statement stays on your own machine. You can prepare several documents for one application in a single sitting without creating an account.

Fixing a rejected upload

When a form still refuses the file after compression, the size is usually not the only rule. Re-read the instructions for the exact format and pixel dimensions: many portals want a JPEG at a specific resolution alongside the 100 KB limit, and a PNG or an oversized image fails even when the bytes are fine. Set the target here to 100 KB for the size, crop to the stated dimensions, and export as JPEG, and the common causes of rejection are covered.
