How it works

Resize JPG in 4 steps

  1. Drop a JPG onto the tool or click Choose File.

  2. Type a width or height - the other side follows automatically.

  3. Or hit a percentage preset for quick scaling.

  4. The preview updates as you type; download when it's right.

When to use it

Camera and phone JPGs are usually 4000+ pixels wide - far more than a website, form, or listing needs. Downscaling a JPG properly makes it dramatically smaller and keeps it sharp; this tool does it on your device with the aspect ratio locked so photos never stretch.

  • Meet exact pixel requirements for avatars, covers, and marketplace listings.
  • Downscale 12-megapixel phone photos to sensible web sizes.
  • Standardize a photo folder to one width with Pro batch.

Format & quality notes

  • Downscaling a JPG both reduces pixels and re-encodes efficiently - a 4000px photo resized to 1600px often drops 80-90% in size.
  • Upscaling can't invent detail; going beyond the original size will look soft.
  • Output is re-encoded at 92% quality - visually transparent for photos.
FAQ

Questions about the Resize JPG.

What size should I resize photos to for the web?

1600-2000px on the long edge covers almost every website use, including retina screens. Full-width heroes rarely need more than 2400px.

Will resizing blur my JPG?

Downscaling with high-quality interpolation keeps photos crisp. Blur only appears when you enlarge past the original dimensions.

Does resizing reduce the file size too?

Dramatically - file size scales roughly with pixel count, so halving both dimensions cuts around 75% of the weight.

Is the photo uploaded?

No - resizing runs in your browser, and the photo never leaves your device.
