Why does Acrobat only let me change the color or size of text?

Adobe's help says a font must be installed on your computer to edit text in it; if it is only embedded in the PDF, you can change just the color or size.

Do I need the font installed to edit a PDF in TweakPDF?

No. New text takes the font embedded in the PDF itself, so there is nothing to install.

Is there a free Adobe Acrobat alternative for editing text?

TweakPDF edits 3 files a month free, every month, with no card and no trial that turns into a subscription.

Does Adobe Acrobat have a free trial?

Adobe's help mentions a seven-day free trial of Acrobat Pro. Read its terms on adobe.com before you start.

What can Acrobat do that TweakPDF cannot?

Acrobat handles forms, export, page editing, redaction and certified signatures; TweakPDF only changes, erases and signs on existing pages.

What Adobe gives for free, and what needs a plan

Adobe's free online tools add text boxes and comments, sign a document or password-protect it. Editing the words already in a PDF is listed on Adobe's plans page under the paid Standard and Pro plans, and its help mentions a seven-day free trial of Acrobat Pro.

For teams, Adobe's business pricing page lists Standard at US$16.99 and Pro at US$23.99 per license a month, on an annual plan billed monthly, with a fee of half the remaining annual commitment if you cancel after 14 days. Prices for individuals are on adobe.com.

Edit PDF text without Acrobat: the font question

Adobe's help on editing text, updated in August 2026, says that to edit text in a specific font, the font must be installed on your computer. If it isn't installed but is embedded in the PDF, you can only change the text's color or size.

PDFs from a designer or a print shop usually carry fonts you don't have.

TweakPDF reads the font from the file, so nothing needs installing. New words get the same font, size and color on the same baseline, and the rest of the line stays put. A letter missing from the embedded font is borrowed from another subset of the same font; only a character the file truly lacks is set in the closest matching font, and the preview warns about it. The old characters are deleted from the file, not covered.

Adobe Acrobat alternative: a side-by-side look

Other ways, and when Acrobat fits better

On a Mac, Preview won't do it: Apple's guide says you can't edit the text of a PDF in Preview, only mark it up. If you have the source in Word or Google Docs, edit it there and export a new PDF, the cleanest fix.

For forms, export to other formats, page editing, redaction or certified signatures, Acrobat or another full editor is the better pick. TweakPDF does not convert, merge or compress files, fill forms, export OCR text, add or delete pages, switch text to a different font or open password-protected PDFs.

To fix a name, date or line in your own document, 3 files a month are free with no card, and Google sign-in is needed only to download. Pro is $6 a month, $24 for six months or $36 a year. Cancel anytime under Manage subscription; a payment is refunded in full within 14 days on request.

Adobe Acrobat is a trademark of its owner; TweakPDF is an independent service and not affiliated with it.
