Use JPG for photos you share or upload, PNG for screenshots, logos and anything with transparency, WebP for website images (25โ35% smaller than JPG/PNG), and AVIF when you want the smallest files and your audience uses modern browsers.

Which format for which job
- WhatsApp, email, government forms: JPG. It is accepted everywhere and small. Convert with PNG to JPG.
- Logos, icons, screenshots with text: PNG, or SVG for logos that must scale.
- Websites and blogs: WebP gives faster pages with almost no visible difference. Try JPG to WebP or PNG to WebP.
- Maximum speed (Core Web Vitals): AVIF, with a JPG or WebP fallback for older software. See JPG to AVIF.
- Printing and archiving: PNG or TIFF to avoid repeated compression.
Why quality drops when you re-save JPG
JPG throws away detail every time it is saved. Editing a JPG and saving it again and again slowly adds blur and blocky artefacts. Keep a PNG or original master copy for editing, and export to JPG or WebP only for sharing.
Can I convert an old format to a new one?
Yes, but converting a JPG to PNG does not restore lost detail; it only prevents further loss. Converting to WebP or AVIF usually makes the file smaller. Use the Image Compressor to shrink any image further.
Frequently asked questions
Is PNG better quality than JPG?
PNG is lossless, so it keeps every pixel, but photos become much larger. For photos, a high-quality JPG looks the same at a fraction of the size.
Is WebP better than JPG?
For websites, yes: WebP is usually 25โ35% smaller at similar quality and supports transparency. Some older apps and forms still expect JPG.
Should I use AVIF on my website?
AVIF gives the smallest files and is supported by current Chrome, Edge, Firefox and Safari; serve WebP or JPG as a fallback for older browsers.
Photo ke liye JPG accha hai ya PNG?
Photos share karne ke liye JPG best hai kyunki size chhota hota hai. Logo, screenshot ya transparent background ke liye PNG use kijiye.
