Frequently asked questions
How do I make an image smaller?
Select the image, set the quality, press compress and download the lighter file.
Which format gives the smallest size?
WebP is often the smallest at good quality; JPG suits photos and opens on every device.
Is it safe for private photos?
Yes. Compression happens in your browser and your images are never uploaded.
How do I reduce an image to 100KB for an upload form?
Lower the quality slider, or convert to JPG or WebP, and compress. Check the result's size and repeat with a lower setting if needed, as there's no exact target-size option for images.
Can I compress images without losing quality?
A high quality setting keeps photos looking almost the same while still trimming file size. Lower settings save more space with more visible loss.
