Frequently Asked Questions
Are my private photos uploaded to any external server?
No! Processing occurs 100% inside your web browser using HTML5 Canvas APIs. Your photos never leave your device.
Which image formats are supported?
We support standard JPEG (.jpg, .jpeg), PNG (.png), and modern WebP (.webp) formats.
What is the recommended quality setting for websites?
A quality level between 75% and 85% usually yields a 60-80% file size reduction with virtually indistinguishable visual difference.
Can I compress multiple images at the same time?
Yes. You can select or drag-and-drop up to 20 images at once and compress them in a single batch.
Will transparent PNGs lose their transparency?
PNG compression maintains transparent alpha channels perfectly without turning backgrounds black or white.
Is there an image resolution limit?
Because compression runs locally on your device's memory, ultra-high-resolution photos (up to 20 MB each) are processed without restriction.
