Frequently asked questions
Are my images uploaded to a server?
No. Compression runs entirely in your browser using the browser-image-compression library — your images are never sent anywhere.
Which formats are supported?
JPG, PNG and WebP images can be uploaded and compressed. The output keeps the same format as the input.
Why didn't the file get smaller?
Some images are already highly compressed, or the quality setting is close to 100%. Try lowering the quality slider for a smaller file.
Is there a file size limit?
No hard limit is enforced, but very large images may take longer to process depending on your device.
