50 KB is one of the most frequently requested limits on exam and job application portals for a passport-style photo. This tool automatically finds the quality (and, if needed, the dimensions) that lands your photo right under 50 KB, without the usual slider guesswork.

Drag & drop files here, or
Up to 100 images, 25 MB each
Drop in a JPG, PNG or WebP file, or select one from your phone.
This page starts with the 50 KB chip selected; change it any time if a different form needs a different size.
You are told exactly what final size, dimensions and quality were used, so you know the result meets the form's requirement before you upload it.
Manually re-exporting an image at, say, 60% quality can land anywhere from 30 KB to 90 KB depending on the photo's detail and resolution — there is no fixed relationship between a quality percentage and the resulting file size. That is exactly the problem this tool solves: it searches quality values automatically until the result is as close to 50 KB as possible without going over.
For most standard passport-style photos (roughly 200×230 to 413×531 pixels, the typical range asked for), 50 KB is comfortably achievable without heavy dimension reduction, so the visual quality usually stays quite good at this target.
If a portal keeps rejecting your upload with a vague "file too large" or "file too small" message, check whether it also enforces a minimum — many exam forms specify a range like "20 KB to 50 KB" rather than just a maximum. Enter that minimum in the optional field here so the result never lands below it.
A busier, more detailed photo needs a lower quality setting to reach the same file size as a simpler one. The tool automatically finds the right quality for your specific photo — it is not a fixed setting.
Yes — add multiple files and they process one after another with a progress bar, then download together as a ZIP.
No. All processing happens locally in your browser using the Canvas API — your photo never leaves your device.
Use the general Compress Image to Exact Size tool, which has the same engine with quick-pick chips for 20 KB, 50 KB, 100 KB, 200 KB, 500 KB, 1 MB, plus any custom value.
