Compress Image to 100KB
Compress images to around 100KB using a target-size slider. Private in-browser processing — no uploads.
Plenty of online forms, job portals, exam registrations, and government sites cap image uploads at 100 KB — and reject anything larger. This tool compresses your JPG, PNG, or WebP to roughly 100 KB directly in your browser, with a target-size slider that does the guesswork for you. Because the work happens on your device with the Canvas API, sensitive documents and ID photos never touch a server. Drop in a single image and download the result in seconds, or turn on batch mode to bring up to five files under 100 KB and grab them as one ZIP. The preview shows the before and after sizes so you can confirm the file will pass the upload limit before you submit. No sign-up, no watermark, and no cost.

Where a 100 KB image limit shows up
The 100 KB cap is one of the most common upload restrictions online. You will usually meet it here:
Government and visa portals
Passport, visa, PAN, Aadhaar, and similar portals frequently require photos and scanned documents under 100 KB.
Job applications
Recruitment sites often limit a profile photo or signature scan to 100 KB before they will accept the form.

Online exam and admission systems commonly ask for a 100 KB photo and a separate signature file.
Profile pictures
Some membership and banking sites enforce a 100 KB avatar to keep their image servers light.

Frequently asked questions
Why do upload forms ask for images under 100 KB?+
A 100 KB cap keeps server storage and page weight down when thousands of people upload documents. Government portals, university applications, and job sites use it most often, and they usually reject files even slightly over the limit.
Will a 100 KB image still be clear enough for an ID or form photo?+
For a typical passport-style or document photo, 100 KB is enough to stay sharp and legible. The preview lets you check readability before downloading, and you can crop tightly to the subject first to give the compressor more detail to keep.
Does this keep my image at the same dimensions?+
Yes. The 100 KB target is reached by adjusting quality at the original dimensions. If your portal also limits width or height, use the Resize to 100KB tool, which reduces pixel size as well.
Is it safe for ID cards and personal documents?+
Yes. Nothing is uploaded — the file is compressed locally in your browser and discarded when you close the tab, so private documents stay on your device.
Can I get several images under 100 KB at once?+
Yes. Batch mode compresses up to five files toward the 100 KB target and lets you download them as a single ZIP.
