Frequently Asked Questions
Does image compression reduce quality?
Compression involves a trade-off between file size and quality. At 80% quality, most people cannot see any visible difference. For photos, 70-80% is ideal. For graphics and logos, use PNG format which is lossless.
What is the best image format for websites?
WebP is the best format for websites — it is 25-35% smaller than JPG at the same quality. All modern browsers support WebP. Use JPG for photographs and PNG only when you need transparency.
Can I compress multiple images at once?
Yes! QuickToolz supports batch compression. Upload multiple images at once and download them all as a ZIP file. Each image is compressed with your chosen settings.
Is there a file size limit?
No daily limits or file count restrictions. Each individual image can be up to 50MB. All processing happens in your browser so performance depends on your device.
Will my images be stored on your servers?
No. Your images are processed entirely within your browser using JavaScript. They are never uploaded to any server. We have zero access to your images.
