Image Compressor

No. Compression happens entirely in your browser using the built-in canvas engine. The image never leaves your device, which also means there are no upload queues, size quotas, or daily limits.

0.7-0.85 is the sweet spot for photos: significant size savings with no visible difference at normal viewing sizes. Drop lower for thumbnails; use 0.9 or above for images with fine text or sharp edges.

PNG is a lossless format, so the quality slider doesn't apply. To shrink a PNG, either reduce its dimensions or convert it to WebP or JPEG. Note that JPEG doesn't support transparency, so transparent areas are flattened to white.

Yes. Re-encoding through the canvas drops EXIF data, including GPS coordinates and camera details. If you only want to remove metadata without re-compressing the pixels, use our Metadata Stripper instead.
