Frequently Asked Questions

How much can I compress an image?
Savings depend on the original file and quality setting. JPEG and WebP photos often shrink 40–80% at medium quality while staying visually sharp.
What is the best format for compression?
WebP usually delivers the smallest files at similar visual quality. JPEG is ideal for photos; PNG is best when you need lossless transparency.
Can I batch compress images?
Yes. Select multiple images at once, apply the same compression settings to the whole batch, preview each result, and download everything in a single ZIP file — all in your browser.
Does compression reduce image quality?
Lossy formats like JPEG and WebP trade some detail for smaller files. Use higher quality settings or compare the preview before downloading.
