Compress an image to 100KB
Many job portals, university admission forms and visa applications cap photo uploads at exactly 100KB. This tool binary-searches JPEG quality until your photo lands at or under that budget — no trial and error.
Drop your photo, and target size mode is already set to 100KB in JPEG (the format that holds this budget fastest and most reliably in the browser). Add a batch if you need several photos at the same cap.
If the closest achievable size is still slightly over 100KB (rare, but possible for very detailed images), the card tells you the exact number reached instead of silently failing — you always see what you got.
Everything runs on your device. Nothing is uploaded to make this happen — the same engine just aims at a smaller number.
Common uses for a 100KB target
A 100KB cap turns up across more than one kind of form, not just one exam board:
- University admission and enrollment portals that reject a photo or scanned ID over 100KB outright.
- Job-portal and recruitment-site photo fields (SSC, banking, PSU-style postings) that pair a 100KB ceiling with a set pixel size.
- E-visa and other online-application photo fields that specify the same 100KB limit, separate from any pixel-size rule.
Batch a folder of these at once and every file lands under 100KB in the same pass.
What if my photo is already under 100KB?
Target size mode still runs, but it won't shrink the file further than it needs to — the search settles on the highest quality setting that still fits inside 100KB, so you get a clean result at or comfortably under the cap, not an over-compressed one. If your photo is already a small JPEG, turn target size mode off and adjust the quality slider directly instead.
