TweakPDF

Change the date on a PDF, fix a name or a number

To change the date on a PDF, click the date, type the new one and press Save. A misspelled name or a wrong number in your own document is fixed the same way: TweakPDF sets the new text in the font embedded in the file, on the same line, and deletes the old characters.

The small fixes people need most

Most corrections to a PDF are tiny. A meeting moved from the 14th to the 21st, a surname lost a letter, a price list still shows last year's price. Rebuilding the document for one line is out of proportion, and the source file is often not at hand.

TweakPDF is made for changes of this size in documents you wrote yourself or keep up to date: a letter, a draft agreement, a form you drew up, a schedule for your team, your own price list.

Edit a date or a number in a PDF and keep the line in place

A date rarely stands alone. It sits inside a line such as “Delivery on March 3, 2026, at 10:00”. When you replace it, TweakPDF draws the new date in the embedded font, at the same size and color and on the original baseline, then adjusts the spacing so the words after it stay where they were.

Numbers work the same way: change a price or a room number, and the figures further along the line keep their positions, so the columns of a schedule or a price list stay aligned. The old digits are deleted from the file, not hidden under a white box.

Names with a letter the font does not have

Names are harder than numbers. A PDF usually carries only the letters its text uses, so a document that spelled “Muller” may have no ü for “Müller” and no é for “José”, and a page set in English may hold no Cyrillic letters at all.

When a letter you type is missing, TweakPDF first looks for it in other copies of the same font inside the document and borrows it from there. Only a character the file truly lacks is set in the closest matching font, and the preview warns you before you download.

Before you start

  • Check what is text

    Turn on Show text. Bright words are text you can click; shaded areas are pictures or blank paper.

  • Scanned pages

    A scan is marked Scanned page. Click a recognized word, or press Text and draw a box over the date, and the new value is drawn into the image itself.

  • What you download

    Preview & download shows the page rendered from the finished file, not a sketch of your edits.

What it does not do

TweakPDF replaces text that is already on the page. It does not add new lines, reflow a paragraph, switch text to another font, fill interactive form fields, add pages or open password-protected PDFs. TweakPDF is only for documents you have the right to change.

Questions about dates, names and numbers

How do I change a date on a PDF for free?
Open the PDF in TweakPDF, click the date, type the new one and press Save. 3 files a month are free, and you sign in with Google only to download.
Can I edit a name in a PDF without changing the font?
Yes. The new name is set in the font embedded in the PDF, at the size and color of the old one. A letter that font lacks is borrowed from another copy of the same font in the file, or set in the closest match with a warning.
Will the rest of the line move if I edit numbers in a PDF?
No. The spacing is adjusted so the text after the new number stays where it was, and the figures in a column stay aligned.
Is the old date still in the file?
No. The old characters are deleted from the PDF, not covered with a white box, so search and copy-paste find only the new date.
Can I change the date on a scanned PDF?
Yes. Click the recognized date or draw a box over it with the Text tool. The area is refilled from the paper around it, and the new date is drawn into the scan in the typeface closest to the printed one.
Do you keep my file?
No. Files are deleted from the server two hours after you stop working, or right away when you press Delete file now.

Fix the date in your own PDF
