Compress Image to 500 KB

Five hundred kilobytes clears most document portals and mail attachments. The 500 KB chip is already on, so the first run starts from it.

Half a megabyte is the ceiling on plenty of application forms, scanned-document portals and email gateways. This page opens with 500 KB already selected, so the first press searches for it: for JPEG and WebP, quality is spent from the top down and pixels are touched only if the floor cannot fit the number. The Result figure quotes the file that was really written rather than the one that was hoped for.

  • Upload the picture; the 500 KB chip is already active.
  • Press Apply Compression without changing the mode for a first attempt.
  • Read the Result figure and compare it with the ceiling you were given.
  • Download from the workspace header once the number is under the mark.

What the options do

Target File Size
Five hundred kilobytes is chosen for you. For JPEG and WebP, encodes at full quality are tried first, quality falls toward the floor only when needed, and the pixel grid is reduced only after that fails.
Reading the numbers
Original is the upload, Result is the encoded file, and Saved is the gap between them. Every figure is measured after the encode, never predicted before it.

Type the ceiling your form demands, apply once, and read the Result before anything else. When the file clears the budget it is ready to send; when it does not, the honest size on screen shows how much further the picture has to come down.

Common questions

Is 500 KB small enough for most uploads?
For scanned documents, forms and typical email attachments, yes. Some portals are stricter and name 100 KB or 200 KB instead, which is why the sibling pages exist.
Will the dimensions shrink to reach it?
Only if quality alone cannot get there. Width and height pass through untouched unless the quality search exhausts itself at the floor and the picture still overshoots.
Does anything leave my device?
No. The file is decoded and re-encoded inside this tab, so the picture never travels to a server and the controls work without a connection.
