Frequently Asked Questions

Find answers to common questions about our tool and how it works.

Typically, you can reduce file sizes by 60-80% without noticeable quality loss. Results vary based on the image content and your quality settings. Photos compress better than graphics with lots of detail.

Compression involves a trade-off between file size and quality. At 70-80% quality settings, most people cannot see the difference. Our tool lets you preview and adjust the quality level before downloading.

WebP offers the best compression with great quality, but isn't universally supported. JPEG is best for photos and has excellent browser support. PNG is lossless but creates larger files.

You can compress images up to 25MB. This limit is based on browser memory, not server restrictions (since we don't upload to servers).

Currently, you can compress one image at a time. For batch processing and advanced features, check out our premium AI Image Upscaler which includes compression.

For web use, 70-80% is optimal. For printing or professional use, 85-95%. For maximum compression (like email), 60-70% works well.
