Compress Image to 30KB — Examination and Recruitment Portals
Thirty kilobytes sits in the band that examination boards and recruitment portals use for the applicant photograph, usually paired with a tighter limit for the signature on the same form.
That pairing is worth noticing before you start. These forms typically want the photograph between 20 and 50 KB and the signature between 10 and 20 KB, and they reject the whole submission if either file misses. Compressing both to the same figure is the most common reason a form comes back.
At 30 KB a photograph has enough room to stay recognisable at the dimensions these portals ask for, which is generally somewhere between 200 and 350 px on the long edge. There is no need to push quality down hard; bringing the dimensions into that range does most of the work on its own.
Before you upload
Check the accepted format as well as the size. Many of these portals accept JPEG only and will refuse a PNG that meets the size limit perfectly.
Why this runs on your own device
The files people compress to a fixed size are rarely trivial — passport photographs, identity documents, certificates, signatures. ImageXpo processes them with WebAssembly inside your browser, so the image is never transmitted, never stored on a server, and never leaves your computer. There is no account to create and nothing to delete afterwards.
Frequently asked questions
How do I compress an image to 30KB?
Set the target size to 30KB and choose your image. Results land at or just below the ceiling rather than exactly on it, because how far a given image compresses depends on its content — a plain background compresses much further than a busy one at the same settings.
The form wants a photo and a signature at different sizes. Do I do them separately?
Yes, one at a time, with the target set for each. The photograph and the signature have different limits on almost every one of these forms, and submitting both at the photograph size is the usual cause of rejection.
Will a 30KB photo be accepted for an exam application?
If 30 KB is within the stated range, yes — these limits are checked automatically on upload. What is not checked automatically is whether the photograph meets the composition rules, so read those too: plain background, face fully visible, recent.
Is my image uploaded to a server?
No. Compression runs through WebAssembly in your browser, so the file stays on your device. Application photographs and signatures are personal documents, and there is no reason for them to travel anywhere.
