The bigger picture: Image & Media
Images and video drive social media and websites, but every platform wants a different size and format. In-browser tools resize, convert and polish media without uploading private photos.
What's changing: Modern formats like WebP and AVIF are replacing heavy JPGs on the web, making pages faster, especially on mobile.
Frequently asked questions
Which format should I use?
WebP gives the smallest files for websites. JPG is the safest for sharing. PNG is for screenshots or images that need transparency.
Is there a file limit?
No fixed limit. Very large photos (50+ MP) depend on your device memory.
Does it remove photo location data?
Yes. Re-encoding removes EXIF metadata, including GPS location.
