Image Compressor
Shrink JPG, PNG and WebP images without uploading them anywhere. Adjust the quality, watch the file size drop, and download — all locally in your browser.
How to use it
- 1Add your images
Drag JPG, PNG or WebP files onto the drop zone or click to choose them. Batches are welcome.
- 2Set the quality
Use the quality slider to balance size against detail. Optionally cap the maximum width or height to shrink large photos further.
- 3Check the savings
Each image shows its original size, new size and the percentage saved, so you can see exactly what you gained.
- 4Download
Save the compressed images with one click. Your originals are never modified and nothing is uploaded.
Smaller images, same great look
Large images slow down websites and fill up inboxes. Compressing them reduces the file size dramatically while keeping the quality you need — you decide the balance with a simple slider.
No uploads, no limits
Everything happens locally in your browser, so there’s no upload wait and no file is sent to a server. There are no quotas and no watermarks — compress as many images as your device can handle.
Frequently asked questions
Are my images uploaded to a server?
No. Compression runs entirely in your browser; your images never leave your device.
Which formats can I compress?
JPG, PNG and WebP. JPG and WebP use quality-based compression; PNG is optimised losslessly.
Will compressing reduce image quality?
For JPG and WebP you control the trade-off with the quality slider — pick a level where the image still looks great but the file is much smaller. PNG optimisation is lossless, so quality is unchanged.
Is there a file-size or count limit?
No artificial limits. Everything runs locally, so the only limit is your device’s available memory.
Can I resize as well as compress?
Yes — set an optional maximum width or height and images are scaled down before compression for even smaller files.
