How it works
How to use the Image Compressor
Drop images
Add one or many JPG, PNG or WebP files. Compression starts immediately.
Tune quality
Slide quality up or down, optionally cap the size, then re-apply to the batch.
Download
Grab each file or a ZIP. Files that can't get smaller are left untouched.
Why BGFixer
Built for real work, not just demos
See every byte saved
Before and after sizes for each file, plus the total saving across the batch.
Smart defaults
PNGs become transparent WebP automatically, and we never return a file bigger than the original.
Bulk by default
Compress an entire product catalogue or blog's worth of images at once.
Nothing uploaded
Compression runs locally, so it's fast even on slow connections and your images stay private.

Frequently asked questions
How much can I reduce image size?
Typical photos shrink by 50–80% at 70–80% quality with no visible difference. Screenshots and PNGs often shrink even more when converted to WebP.
Will compression reduce image quality?
Lossy compression removes detail the eye barely notices. Keep quality above 70% for photos to avoid visible artefacts.
Can I compress images to a specific size like 100 KB?
Lower the quality and turn on Downscale large images until each file is under your limit. The size of every file is shown as you go.
Is there a file limit?
No. Because processing happens on your device, there is no limit on the number or size of images.
Are my images safe?
Yes. Images are processed in your browser and never uploaded to any server.
