Frequently Asked Questions
How much can I compress an image without losing quality?
For JPEG images, 70–80% quality is typically the sweet spot — up to 70% size reduction with no visible quality loss. PNG compression is lossless.
Will compressing change the image dimensions?
No. Image dimensions (width and height in pixels) stay exactly the same. Only the file size changes.
Which image formats can be compressed?
JPG and JPEG images are compressed using lossy JPEG encoding. PNG files use lossless compression. WEBP files use WEBP encoding.
Can I compress multiple images at once?
Absolutely. Drop as many images as you need — all are compressed in one batch and available for individual or bulk download.
