Frequently Asked Questions
Is my image uploaded to a server?
No. All compression happens in your browser using the Canvas API. Your image never leaves your device.
Why does PNG ignore the quality slider?
PNG is a lossless format — it always preserves full image quality. For size reduction, try converting to JPEG or WebP.
What is the maximum file size?
This tool supports images up to 20 MB. For best performance, images under 5 MB are recommended.
Which format produces the smallest files?
WebP typically produces the smallest files with good quality. JPEG is also effective for photographs. PNG is best when you need lossless quality.
