Print Instructions

How to print at 100% scale

CHROME / EDGE / FIREFOX
  1. Open the downloaded PDF
  2. Press Ctrl+P (or Cmd+P on Mac)
  3. Set scale to 100% or "Actual Size"
  4. Disable "Fit to Page" or "Shrink"
  5. Print!
ADOBE ACROBAT
  1. Open the PDF in Acrobat
  2. File → Print
  3. Under "Page Sizing", select Actual Size
  4. Confirm paper size matches
  5. Print!
⚠️ Critical: Never use "Fit to Page" or "Shrink to Printable Area" — these rescale your image and break the precision you set in ToScale. Always print at exactly 100% / Actual Size.
FAQ
Why does my print look different to the preview?
Make sure you're printing at 100% scale / Actual Size. Most printers default to "fit to page" which shrinks your content. Disable this in your print dialog.
What file formats can I upload?
ToScale accepts PNG, JPG, WEBP, and SVG files. For the sharpest results, upload the highest resolution image you have.
Is ToScale free to use?
Yes — the web app is completely free with no sign-up required.
Does it work offline?
Once the page has loaded, the editor works fully offline. Your images never leave your device — all processing is done locally in your browser.
