What changes when a PDF page becomes an image

2026-10-01

A PDF is a document: text, fonts, links, form fields and structure, laid out on pages. A JPG or PNG is a picture: a grid of coloured pixels. PDF to Image draws each selected page at the resolution you choose, so what you can see on the page becomes pixels, and the document’s working parts stay behind. This is the same for both formats.

What ends up in the image

• The page’s visible content: text, photos, drawings and backgrounds, drawn by the tool’s PDF engine at the chosen resolution.
• Filled-in form fields, showing the values you can see on the page.
• Markup that is visible on the page. In our tests, a shape drawn on the page as an annotation appeared in the image, one the PDF marks as hidden did not, and a sticky note showed only its small note icon — the comment text, which a PDF viewer shows in a pop-up, is not in the image.
• The visible mark of a signature, where the PDF draws one.
• The page’s own crop and rotation, as a PDF viewer would show them.

The image is drawn by the tool’s own PDF engine. Fonts, fine lines and the resolution affect how close it comes to what you see in another viewer; it is not a copy of any particular app’s screen.

What stays behind

• Selectable and searchable text. Words become pixels. You can no longer copy or search them, or have them read aloud from the file. PDF to Image does not run text recognition (OCR).
• Working links. A link may still look like a link, but it goes nowhere.
• Fillable forms. Values you can see are drawn into the image; the fields can no longer be filled in or changed.
• Document structure, such as bookmarks, attachments, metadata, layers and the tags that screen readers rely on.
• Scalable drawing. In a PDF, text and vector graphics are redrawn for every zoom level. In an image they have a fixed pixel size; the resolution you choose decides how far you can zoom before edges soften.

Choosing PNG does not bring any of these back. PNG stores the drawn pixels without loss — it does not keep the PDF’s text, links or forms.

A white background, no transparency

Every page is drawn on white, the way PDF viewers show it. JPG cannot hold transparency at all; PNG could, but PDF to Image does not make transparent PNGs. If you place an image of, say, a logo from a PDF on a coloured background, it comes with a white rectangle around it. Removing a background is a separate editing step that this tool does not do.

Signatures and certification

If a PDF is digitally signed or certified, the signature’s visible mark can appear in the image, but its validity does not travel with it — an image cannot carry a cryptographic signature. PDF to Image shows a short note when you open a signed or certified document, and another when the PDF has form fields. If the signature matters, share the original PDF.

If you rely on accessible PDFs

Tagged PDFs carry reading order and structure for screen readers; an image carries none of that. If you or the people you share with use assistive technology, share the original PDF alongside the images, or instead of them.

Keep the original

The conversion does not change your PDF — it is only read, on your device. Keep it: it is the version with the text, links and structure intact, and you can make new images from it, in either format and at another resolution, whenever you need them.
