Frequently Asked Questions — Image Compressor
Does image compression reduce quality?+
Lossy compression (JPEG) slightly reduces quality in exchange for a much smaller file size. Lossless compression (PNG, WebP) removes metadata and redundant data without any visible quality loss.
Which image format gives the smallest file size?+
WebP is typically 25–35% smaller than JPEG at the same quality. AVIF is even smaller but has less browser support. For photos, use WebP or JPEG; for graphics with transparency, use WebP or PNG.
Is my image uploaded to a server?+
No. All compression is done using the HTML Canvas API directly in your browser. Your images never leave your device.
What is the ideal image size for a website?+
For web use: hero images should be under 300 KB, blog images under 150 KB, and thumbnails under 50 KB. Page images are a leading cause of slow load times.
What does DPI mean and does it affect web images?+
DPI (dots per inch) is only relevant for print. For web and screen display, only pixel dimensions and file size matter. You can safely reduce DPI for web-only images.
Can I compress animated GIFs or WebP?+
This tool focuses on static images (JPEG, PNG, WebP). For animated GIFs, consider converting to WebP animation or MP4 video for much better compression.
