Compress image to 100 KB
Many application forms only accept photos under 100 KB. Drop your photo in, and download a copy that fits, with the best quality possible at that size.
To compress an image to 100 KB, choose it above and tap Download: the target is already set to 100 KB. The tool keeps the highest quality that fits and only reduces the dimensions if needed. Nothing is uploaded.
How to compress a photo to 100 KB
- Choose your photo above, or drop it on the box. You can do several at once.
- Check the target size. It's set to 100 KB; type another number if your form asks for something different.
- Keep JPEG as the format: it's accepted everywhere. Pick WebP only for websites.
- Tap Download next to the result. The file name ends in its new size so you can find it.
How it works
JPEG and WebP photos have a quality setting. The tool tries different settings and keeps the highest quality that still fits your target, so the photo looks as good as it can at that size. If even a low quality is too big (a huge photo squeezed into a tiny limit), it shrinks the width and height step by step until it fits. You'll see the new size next to each photo before you download it.
Where you'll need it
- Government, passport and visa application portals.
- College admission and scholarship forms.
- Job portals and HR systems that cap photo uploads.
- Profile pictures on sites with strict limits.
Some forms ask for a range, such as 20 to 100 KB. Aim a little under the maximum, for example 90 KB, so the file is safely accepted.
Keep them locked, offline
Sealcloak encrypts your photos, videos and files on your phone. No account, no cloud, no internet permission.
Private by design
The tool runs entirely inside this browser tab. Your photo is opened, edited and saved on your own device, and it is never sent to a server, so there is nothing for anyone to keep, scan or leak. No account, no watermark and no limit on how many photos you do. It even keeps working if you switch off your internet after the page has loaded.
Tips for the sharpest result
- Crop first. Cutting away empty background leaves more of the size budget for the part that matters. Use the crop tool, then compress.
- Set the longest side if the form also lists pixel dimensions. Smaller dimensions at good quality usually look better than big dimensions at low quality.
- Screenshots and scans of text compress very well as JPEG once they're cropped to the page.
Photos you never want anyone to see are better kept out of the gallery altogether. See how to hide photos on Android, or how Sealcloak keeps them encrypted on your phone.
Frequently asked questions
Will compressing to 100 KB make my photo blurry?
Only as much as it has to. The tool keeps the highest quality that fits in 100 KB, and only reduces the dimensions if quality alone isn't enough. Cropping away background first leaves more detail for the subject.
Is my photo uploaded to a server?
No. Everything happens in your browser on your own device. The photo is never sent anywhere, so it can't be stored, scanned or leaked by this site.
Does it work on Android and iPhone?
Yes. It works in Chrome, Samsung Internet, Firefox and Safari on phones, tablets and computers. iPhone HEIC photos are converted to JPEG as part of the process.
Can I compress several photos at once?
Yes. Choose or drop as many as you like. Each one is compressed to the same target size and gets its own download button.
My form says between 50 KB and 100 KB. What should I type?
Type about 90 in the target size box. The result will be just under 100 KB and comfortably above the minimum, which forms accept most reliably.
