Frequently asked questions
Are my images uploaded to a server?
No. The compressor uses your browser's Canvas API to compress images locally. No file is ever transmitted over the internet.
Which formats are supported?
Input: JPG, PNG, WebP, GIF, HEIC (Chrome 104+, Safari 17+). Output: WebP (recommended for web), JPEG, PNG.
What is the difference between quality mode and target size?
Quality mode applies a fixed compression ratio (1% to 99%). Target size mode automatically finds the right compression to reach a precise file size in KB or MB.
Can I compress multiple images at once?
Yes. Drop as many images as you want. Use "Download all (ZIP)" to package all compressed images into one archive.
