Under 100 KB, still looking good
At 100 KB most photos look practically the same as the original on a phone or laptop screen, which makes it a popular limit for document portals, online shops, classifieds, forums and email newsletters. Images from modern phones are 20–50 times bigger than that. This page loads the compressor with a 100 KB goal: add your pictures and each one is re-saved as a JPG with the highest quality that keeps it under the limit, reducing dimensions only when necessary. It all runs locally in your browser, with no uploads and no watermark.

How to reduce an image to 100KB
- 1Select or drop your photos. You can add more later with Add more.
- 2Leave 100 KB in the size box.
- 3Watch each row go from Working… to its new size.
- 4Save each image with its download icon, or grab them all as one ZIP.
Where a 100 KB image limit is common
- Document and photo uploads on government and education portals.
- Online marketplaces and classified ad sites.
- Forum avatars and signature images.
- Newsletters and emails, where small images load faster.
Getting the most out of 100 KB
Crop away parts of the picture you don't need before compressing: every pixel you remove leaves more of the 100 KB for the part that matters. Straighten and brighten dark photos in your phone's editor first, because dark, noisy images need more data to look clean.
Batch compression for shops and sellers
If you list products online, drop all your product photos at once. Every image is brought under 100 KB individually, keeping the best quality each one allows, and the ZIP download keeps their original names with a .jpg ending so they are easy to match up.
Checking the result
Each row shows the old size, the new size, the percentage saved and the final width and height in pixels. Open the downloaded file and look at it before you upload it anywhere, especially for documents with small print that must stay legible.
Private by design
Unlike many online compressors, nothing is sent to a server: the images are processed inside your browser tab. That makes it safe for ID documents, family photos and unreleased product pictures.

Frequently asked questions
Will people notice the difference at 100 KB?
Rarely on a screen. At this size a typical 12-megapixel phone photo is scaled down to around one or two megapixels and saved at medium quality, which is still plenty for viewing on screens. Differences show mainly if you zoom in or print large.
Can I compress a scanned document image to 100 KB?
Yes, and documents compress especially well because of their white backgrounds. If you have several pages and need them in one PDF under 100 KB, use JPG to PDF under 100KB instead.
Why did one photo stay above 100 KB?
If the row says it couldn't reach 100 KB, the picture was already tiny or unusually detailed. That is very rare at this size; try cropping it, or pick a slightly higher target.
How long does it take?
About a second per photo on a laptop and a few seconds on an older phone. The rows update one after another, and the heading counts how many are done.
Will the date and location from my camera be kept?
No. Re-saving the photo through the browser drops camera metadata such as date, device and GPS location, which is good for privacy when you share pictures online.
Can I undo the compression?
The compressed copy is a new file; your original photo is never changed. Keep the original if you may need full quality later.
