Keeping screenshots readable once they are a PDF
Screenshots pile up as the record of a conversation, a booking, a payment or an error message, and sooner or later someone wants them as one document. They are not photos: they are mostly lettering and flat color, they can be very tall, and they often show things meant for no one else. Each of those changes what a good conversion looks like.

Which tool you need
Chat threads, receipts or confirmations kept as a record
Screenshot to PDF. Each capture becomes a page in the order you set, as sharp as it was on screen.
A capture saved as HEIC on an iPhone
Image to PDF, opened on the iPhone itself or in Safari on a Mac. This page takes PNG, JPG and WebP captures only.
Someone needs to search or copy the words
Ask for the original message, page or file instead. A screenshot holds a picture of the words, and this converter does not read them back out of it.
A long scrolling capture that must print on ordinary paper
Choose A4 or US Letter and fit the picture inside the page, and expect small type: the whole capture shrinks onto a single sheet, because it is never divided.
Screenshots that belong with PDFs you already have
Merge PDF, once the screenshots are a PDF of their own.
Why lettering is the hard part
Photo compression smooths away fine detail that the eye barely misses in a landscape and notices at once around the edges of letters. Phones and computers save screenshots as PNG by default to avoid that, and a PNG capture keeps every pixel here too; a WebP capture is decoded and stored the same way, and a JPG one is placed as it was saved, neither improved nor made worse.
The resolution a capture claims is ignored. Screen captures usually record 72 or 96 pixels per inch whatever their real sharpness, so pages are sized at 150 pixels to the inch instead, which keeps a phone capture a sensible size on screen and on paper.
Tall captures and the page they get
A scrolling capture of a long chat or web page becomes a single page as tall as the capture. A very long one is placed on a page capped at about 69 inches on its longer side, a length PDF readers open without complaint, and every pixel is still there, only packed more closely.
What a screenshot gives away
Screenshots catch more than the part you meant: notification banners, account names, balances, the other half of a conversation. The conversion happens in your browser, so none of that is sent to a server to be turned into a PDF.
It does go into the PDF, exactly as captured, and nothing here blurs or blacks out part of a picture. Crop or mark up the capture in your phone's or computer's photo editor before adding it, and look over the preview before you share the result.
What to know before you start
- PNG, JPG and WebP captures only; HEIC ones go through Image to PDF.
- Text in a screenshot is part of the picture and cannot be selected.
- A long capture is never divided across pages.
- Nothing here hides or redacts part of a screenshot.
