Image compressor
Reduce image size with format-aware quality controls.

Drop JPEG or WebP images to compress
PNG is lossless, so choose JPEG or WebP to reduce PNG size. Metadata is removed during compression.
How it works
Step 1
Load the originals
Drop in one image or a whole batch; the originals stay on your device while the browser does the work.
Step 2
Set the quality level
The quality control follows the output format, and PNG or WebP can be set to lossless when every pixel has to stay intact.
Step 3
Compress and save
Each result is encoded locally, so batch size is limited mostly by your device memory and every download is a plain file save.
Frequently asked questions
Does compressing an image reduce its quality?
Lossy formats like JPEG, WebP, and AVIF lose detail as quality drops; lossless PNG and lossless WebP keep the pixels intact and shrink less.
Can I compress many images at once?
Yes, but the batch is limited by available memory because every file is decoded in the tab — a few dozen large photos at a time is realistic.
Is my data safe when I compress a photo?
Compression runs entirely on your device, so the photos never leave your computer and no copy is stored on any server.
Files are processed on your device and never uploaded for conversion.
