JPG vs PNG vs WebP: Which Format Should You Use?
JPG · photographs
Lossy compression suits photos and can produce compact files. JPG does not preserve transparent backgrounds.
PNG · transparency and graphics
PNG supports lossless storage and transparency, useful for text and graphics. Files may be larger than photographic JPGs.
WebP · flexible compression
WebP supports lossy and lossless encoding, plus transparency. The best format depends on the image and where you use it.
Quality is not a savings percentage
An 80% quality setting does not mean an 80% reduction in file size. Results depend on image content, format and encoder.
Keep original copies. Repeated lossy encoding can degrade detail. PNG optimization is not the same as JPG quality adjustment, and converting an already optimized image may not make it smaller.
Frequently Asked Questions
What is an image compressor?
It reduces image storage through encoding or optimization. Results depend on the image, format and quality settings.
How can I compress JPG images online?
Choose JPG images, set the output format and quality, compress, then compare and download the results.
Can I compress PNG without losing transparency?
PNG and WebP can retain transparency. JPG does not support transparency and uses a background color.
Does image compression reduce quality?
Lossless encoding preserves image data; lossy encoding can remove detail. Lower quality is not a fixed file-size reduction, and results vary with the encoder and image.
Can I compress multiple images at once?
Yes. Add multiple supported images, compress them and download the results individually or together as a ZIP.
Are my images uploaded to a server?
Files are read and processed locally in your browser, without uploading them to a server. Keep your original files.
