Good to know
Percentage or pixels
Percentage scales every image by the same amount, handy for a folder of photos in different sizes. Pixels sets a width, a height or both: with Keep aspect ratio on, each image fits inside that box without stretching; turn it off to force an exact size.
Sharp results when shrinking
Big reductions happen in several halving steps, so fine detail and text stay crisp instead of turning jagged. Keep each file's format with Original, or switch to JPG, PNG or WebP while you resize.
Does resizing reduce the file size?
Usually: fewer pixels make a smaller file. To shrink the file further without changing the pixel size, run the result through Arche's optimizer.
Can I make an image bigger?
Yes, up to 200% or any size up to 16,384 px per side. Enlarging can't add detail, so the result looks softer than the original.
Are my images uploaded?
No. The conversion runs inside your browser, so your images stay on your device. Files are only uploaded if you choose to optimize them with Arche, and those are deleted within 48 hours.
What is Arche?
Arche makes JPEG, PNG and WebP images smaller without changing their format or pixel size, and strips metadata such as EXIF location. It is free without an account; Pro raises the batch limits.
