Compress image to 100KB
Fit photos and scans under 100KB with automatic quality search, batch processing, and no server upload.
Exact-size compressor
Files stay on this device
Advanced settingsResize, crop, quality
Dimensions never upscale. JPEG fills transparent pixels with white. GIF and animated WebP inputs become a static first frame.
Ready when you are. No image data is sent over the network.
On-device processing
No image upload endpoint exists.
Measured output
Success uses the real output bytes.
Batch ready
Process 20 files and download a ZIP.
Pick the limit your form asks for
Every page uses the same private compressor with the target already selected. You can still enter a custom value at any time.
A balanced target for forms and profiles
One hundred kilobytes leaves enough room for a clear, moderately sized photo while remaining small enough for many upload systems.
Where this target helps
Application photos, ID images, and profile pictures
Readable receipts and compact document scans
Email-ready images and lightweight web content
Highest useful quality, without guesswork
Search quality first
JPEG and WebP outputs use a binary search to find the highest encoder quality that stays below 100KB.
Resize only when required
If quality alone cannot reach the limit, the engine reduces dimensions and searches again. It never upscales the source.
Show the honest result
Every download reports its measured bytes, dimensions, savings, and whether the requested maximum was reached.
Choose the right format
- JPEG
- Broadly accepted and efficient for photographs. Transparency becomes white.
- WebP
- Often smaller at similar quality and can preserve transparency.
- PNG
- Lossless and good for sharp graphics, but harder to fit under tiny limits.
Questions before you compress
How does the compressor find the best 100KB result?
It runs a binary search across encoder quality levels and keeps the highest-quality output whose measured size is at or below 100KB.
Can I compress several photos together?
Yes. Add up to 20 images, process them as one batch, then download each result or one ZIP archive.
Do my files leave this device?
No. Decoding, resizing, compression, previews, and ZIP creation happen inside your browser.
Your images stay yours
The compressor has no image upload API. Analytics, when allowed, records only page and tool events without file names or contents.
