Frequently Asked Questions
Everything you need to know about the Image Compressor.
How does image compression work?
The compressor redraws your image and saves it with a smarter encoding at the quality you choose. JPG and WebP compression removes detail the eye barely notices, which dramatically reduces file size. If a file cannot be made smaller, the original is kept.
Will compression reduce my image quality?
At 70 to 80 percent quality, most people cannot see a difference on screen. Lower settings save more space but may show slight softness or blocky areas, especially in smooth gradients. Compare the preview before downloading.
What is the best format for websites?
WebP usually gives the smallest files at the same quality and is supported by all modern browsers. JPG is best for photos when you need maximum compatibility, and PNG is best for logos and graphics that need sharp edges or transparency.
Is there a file size or number limit?
There is no fixed limit, because everything runs on your own device. Very large images, such as 50 megapixel photos, may take a few seconds each on older phones.
How do I compress an image to under 100 KB for a form?
Set the quality to around 60 to 70 percent and choose a max width of 1200 pixels or smaller. Most photos then drop well under 100 KB. If not, lower the width again or use our Image Resizer for exact dimensions.
