Tips
80% quality is the sweet spot, visually identical to the original but significantly smaller.
For web images, 60–75% quality reduces file size by 50–70% with minimal visual loss.
PNG files with transparency are preserved. For photos, converting to JPG gives better compression.
All processing happens in your browser. Your images are never uploaded to any server.

Frequently Asked Questions

Common questions about online image compression

Does compressing an image reduce its quality? +

It depends on the quality setting you choose. At 80–90%, most people cannot tell the difference between the original and compressed image, while file size drops by 40–70%. Lower quality settings (below 60%) will produce noticeable artifacts, especially on photos.

What is the difference between compressing JPG and PNG? +

JPG and WEBP use lossy compression — you control the quality level and trade quality for file size. PNG uses lossless compression, so quality is always preserved. Our tool re-encodes PNG files at their best lossless quality, which may not significantly reduce size for already-optimized PNGs.

Are my images uploaded to a server? +

No. Everything happens inside your browser using the Canvas API. Your images are never sent to any server. This also means you can use the tool offline after the page loads.

What is the best image format for the web? +

WEBP is generally the best format for web use — it produces smaller files than JPG at the same quality and supports transparency like PNG. Most modern browsers support WEBP. For maximum browser compatibility, JPG (for photos) and PNG (for logos/graphics with transparency) remain reliable choices.

Can I compress multiple images at once? +

Yes. You can compress up to 5 images at once. All compressed files can be downloaded individually or as a single ZIP file using the "Download All as ZIP" button.
