Frequently Asked Questions
How does image compression work?
Our tool uses browser-based Canvas API to re-encode images at optimized quality levels, reducing file size while preserving visual quality.
What is the quality slider?
The quality slider (1-100%) controls compression intensity. 80% is recommended for most images — visually lossless with significant size reduction.
How does Target Size work?
Enter a target size in KB and our binary search algorithm will find the optimal quality level to match your desired file size (within ±5% tolerance).
Can I convert formats?
Yes! Convert between JPEG (smallest for photos), PNG (supports transparency), and WebP (best overall compression).
What formats are supported?
JPG/JPEG, PNG, WebP, GIF, BMP, TIFF, SVG, HEIC, HEIF, AVIF, ICO, JFIF, APNG, and more.
Are my images uploaded to a server?
No! All compression happens in your browser using the Canvas API. Your images never leave your device.
Is there a file size limit?
Up to 50MB per image. You can compress unlimited images in a batch.
