How to Use This Tool — Q&A
Does this upload my photos anywhere?
No. Everything runs locally in your browser using the Canvas API — your images never leave your device.
What's a good quality setting?
70–80% usually gives a very close to lossless look with a large size reduction. Go lower (40–60%) for thumbnails or web previews.
Can I compress PNG files?
Yes, PNG is supported for input. Note that PNG is lossless, so for the biggest size savings on photos, convert the output to JPEG or WebP.
Why is WebP recommended?
WebP typically produces 25–35% smaller files than JPEG at the same visual quality, and is supported by all modern browsers.
Is there a file size or count limit?
No hard limit — it depends on your device's memory. Most browsers comfortably handle dozens of images at once.
