Compress images, not quality
Shrink JPG, PNG and WebP file sizes with a live quality preview, so you land the smallest file that still looks great, right in your browser.
Compressed in three steps
- 1
Drop your image
Pick a file or drag it onto the page. It opens instantly, nothing is sent anywhere.
- 2
Dial in quality
Drag the slider and watch the output file size drop in real time. Stop at the sweet spot.
- 3
Export & download
Save the smaller JPG, PNG or WebP, ready to share or upload.
See the size live
The output size updates as you drag. No guessing, no re-uploading to check.
JPG, PNG & WebP
Pick the best format. WebP often halves a JPG at the same visual quality.
Private by design
Compression runs in your tab. Your photos are never uploaded anywhere.
Your photos never leave your device
Most online compressors upload your files to a server. Photoyam has no backend at all: your image is compressed right in this tab, so private and sensitive photos stay yours. No size limit but your browser's memory.
