START WITH THE FILE LIMIT
Should you choose 100KB, 500KB, or 1MB?
Start below the limit set by the destination and compare the downloaded result. For document photos, readable small text and stamps matter more than the smallest possible file. For ordinary photos, 500KB is often a useful first comparison point.
USING A TARGET SIZE
A target KB is a goal to get under
The compressor adjusts quality first and can reduce image dimensions step by step when needed. If an original is already small, or the requested output format would make it bigger, the original can be kept as the result.
For a 100KB or 500KB upload
- Check the required format and maximum file size.
- Set a target slightly below the limit.
- Zoom into the result and check faces, document text, and QR codes.
For a batch of images
You can process up to 50 images at once. Results download as a ZIP file. If a file cannot be processed, successful results are still created and the failed count is shown.
Frequently asked questions
Will the result be exactly 100KB?
The tool aims to get under the target, but the result varies with color, resolution, and file type. Check the actual result size.
Can compression make a photo blurry?
Very small targets can reduce quality or pixel dimensions. Zoom in on important text and faces before uploading.
Will it change my original?
No. The compressed image is created as a new file.
PHOTO SIZE GUIDE
What photo size should you choose?
Upload limits vary by site. Use these targets as a practical starting point, then compare the downloaded result. Document photos, portraits, and transparent PNG files can need different sizes.
A useful starting point for balancing size and clarity.
Check the destination limit first.
When an upload says the file is too large
- Check the maximum size and accepted file types stated by the destination.
- Choose a target below that limit: 100KB, 500KB, or 1MB.
- Download the result and confirm both the actual size and visual clarity.
- If it still fails, check the extension, image dimensions, and any additional destination rules.
Choose the right image format
A practical default for photos and portraits.
Common for transparent images and sharp graphics.
Consider it as an output format when reducing file size for the web.
Frequently asked questions
Can I make a photo exactly 100KB?
The tool adjusts quality and dimensions to get close to or under the chosen target. The final size can be smaller depending on the source image.
Will reducing a photo to 100KB make it blurry?
It depends on the source. For photos containing text, compare a 500KB or 1MB result before submitting it.
Are my photos stored on a server?
Photos are processed in your browser. The tool does not upload them for separate server storage.
