About
The school form, the lease, the insurance claim. You just need to fill it in, sign it and send it back. Udfyld does that in a minute, for free.
FILL IN FORMS
• Real form fields are filled directly: text, check boxes, radio buttons and lists.
• Flat PDFs without fields: tap where you want to write. The text sits neatly on the line.
• Add a date, a tick or a cross with one tap.
SIGN
• Draw your signature and initials once with your finger.
• Place them and resize them where you need to sign.
• Your signature is only stored on your iPhone.
PAGES
• Move, rotate, duplicate, delete and extract pages.
• Merge several PDFs into one file.
• Turn photos into a PDF.
COMPRESS
• Make big PDFs small enough to email: Small, Medium or Original.
• See the new size before you save, e.g. 12.4 MB → 1.8 MB.
• Pages with text are never turned into images, so text stays sharp.
SAVE AND SHARE
• The original is never touched: Udfyld saves a copy unless you choose to overwrite.
• Share with Mail, Messages, AirDrop or save to Files.
• Lock the fields so the recipient sees exactly the same, and add a password if you like.
• Open straight from Files, Mail and Safari with "Open in Udfyld".
YOUR FILES STAY WITH YOU
No account, no ads, no subscription. Udfyld sends nothing over the internet: everything happens on your iPhone.
