Frequently asked questions

How do I compress an image without losing quality?
Upload your image to ImgToolz and adjust the quality slider. Our smart compression reduces file size while preserving visual quality — most users can't tell the difference.
How much can I reduce my image file size?
Typically 50–80% reduction depending on the original file. A 5MB photo can often be compressed to under 500KB with no visible quality loss.
Which image formats can I compress?
JPG, JPEG, PNG, and WebP are all supported. The tool automatically picks the best compression method for each format.
Does compressing an image reduce its dimensions?
No. Compression only reduces file size, not dimensions. Use the Resize Image tool if you want to change the pixel dimensions.
Is the compressed image stored on your servers?
No. All processing happens directly in your browser. Your images never leave your device.
Can I compress multiple images at once?
Currently the tool processes one image at a time for maximum quality control. Batch processing is coming soon.
