Three quick steps
Make a heavy photo light in seconds
Trimming an image down to size is a drag-and-drop job, with a clear before-and-after for every file.
- 1
Drop in one image or a whole batch of JPG, PNG and WebP files — they're read straight in your browser, ready to compress.
- 2
Pick a preset, or open Advanced to fine-tune quality, max resolution and output format per file — the estimated size updates live as you adjust.
- 3
Press Compress (one file or the whole batch), then download the smaller images individually or as a single zip.
Common needs
When a photo is simply too big
Oversized images slow pages down and bounce off attachment limits — these are the moments shrinking them pays off.
Getting product or gallery photos light enough to load fast on a web page.
Squeezing a batch of images under an email or upload size limit.
Lightening phone photos before posting or sending them on.

Quick answers
Image compression questions, covered
- How do I compress an image?
- Drop in a JPG, PNG or WebP (or a whole batch), pick a quality level and each image is re-encoded and scaled to a smaller file — then download them one by one or as a single zip.
- Will compressing reduce image quality?
- Compression is lossy, so a smaller file means some loss of detail. Choose a higher quality level to keep images crisp, or a smaller one for the tiniest file — you can see the before and after size before downloading.
- Can I compress several images at once?
- Yes. Add as many images as you like and each is compressed automatically — then grab the whole batch as one zip.
- Are my images uploaded to a server?
- No. Compression runs entirely in your browser, so your photos never leave your device.
Local only
Photos are compressed on your machine
Every image is re-encoded inside your browser, so the pictures you're shrinking are never uploaded — handy when the bulky photos you need to send happen to be private ones.
