Compress a photo to 100 KB without uploading
If a registration portal or profile upload told you to stay under 100 KB, this page targets that cap. It keeps as much detail as it can while finishing under 100 KB.
No upload. Files never leave your device.
Drop images here
JPEG, PNG, WebP, AVIF, GIF, BMP, and TIFF are welcome. Multiple files are fine. Output is always JPEG so the size cap can be met.

No files yet. Nothing is sent to a server when you add them.
Exam registration and portal profile photos
Exam registration, campus systems, and many job-application portals ask for a profile or identification photo and then reject files that are slightly over the cap. A 100 KB JPEG is usually enough for a clear head-and-shoulders picture if you crop first.
This page does not change print size or DPI metadata; it changes the file weight. Always follow the portal’s own crop, background, and document instructions, and use this tool for the 100 KB size cap. Nothing leaves your browser.
Frequently asked questions
Does this upload my photo?
No. Compression runs in a Web Worker on your device. Nothing is sent to a conversion server.
Will this change the DPI or print size of my photo?
No. The page targets the file’s size in bytes, not dots-per-inch or printed dimensions. If a portal also asks for a specific pixel width or a paper size, set that separately before or after you compress.
Is 100 KB enough for an exam or job-portal portrait?
For a cropped head-and-shoulders photo it usually is. A wide, uncropped original may need to be resized, which can soften fine detail. Crop first when the portal wants a face-and-shoulders frame.
Why is the output JPEG?
JPEG is widely accepted by registration portals and stays small enough to meet a 100 KB cap. PNG is often larger than 100 KB for a photograph.
Can I compress many files at once?
Yes. Add a batch, compress, then download a ZIP. Each file is brought under 100 KB on its own.
