PDF to Image: How It Works

Converting PDF pages to images produces a fixed picture of each page. That is exactly what you want for a thumbnail, a slide or a preview — and exactly what you do not want if anyone needs to select, search or read the text.

What you gain and lose

	PDF	Image
Text	Selectable and searchable	Pixels only
Scaling	Sharp at any zoom	Blurs beyond native resolution
Accessibility	Readable by screen readers	Inaccessible without alt text
Embedding	Needs a viewer	Works anywhere an image works
File size	Efficient for text	Larger per page

The accessibility point deserves emphasis. Converting a text document to images makes it unreadable to anyone using a screen reader, and unsearchable for everyone. If the reason is 'so people cannot copy the text', it is worth knowing that it also stops people who need assistive technology from reading it at all — and that anyone determined to extract the text can simply run OCR.

Choosing a resolution

Purpose	DPI	A4 page becomes
Thumbnail	72	≈ 595 × 842 px
Screen viewing	150	≈ 1240 × 1754 px
Presentation slide	150–200	Sharp on a projector
Print	300	≈ 2480 × 3508 px
Archival	600	Very large files

Resolution is fixed at conversion. Choosing 72 DPI and later needing print quality means converting again from the PDF — which is fine if you kept it, and impossible if you did not.

Format

PNG — lossless, sharp text edges, larger files. The right choice for pages containing text.
JPEG — smaller, but ringing artefacts appear around text. Acceptable for image-heavy pages, poor for documents.
WebP — smaller than PNG at similar quality, if the destination supports it.

The instinct to use JPEG for size is usually wrong here. Text on a white background is exactly the content JPEG handles worst, and PNG often compresses such pages better anyway.

Legitimate reasons to convert

Thumbnails and previews in a listing.
Inserting a page into a presentation or document that cannot embed PDF.
Posting a page to social media or a platform that only accepts images.
Extracting a diagram or chart for reuse.
Sharing where the recipient has no PDF viewer.

Extracting embedded images instead

If you want the photographs from a PDF rather than pictures of its pages, that is a different operation — extracting the embedded image objects at their original resolution. Rendering the page and cropping gives you a lower-quality version with the page's background baked in. Look for an image-extraction function rather than a page-rendering one.

Conversion here happens in your browser, so nothing is uploaded.

Frequently Asked Questions

What resolution should I use?

72 DPI for thumbnails, 150 for screen viewing and presentations, and 300 for print. The resolution is fixed at conversion, so choose for the largest use you anticipate — keep the PDF so you can convert again.

Should I use PNG or JPEG?

PNG for pages containing text, because JPEG creates ringing artefacts around sharp edges. JPEG only for image-heavy pages. Text on white is exactly the content JPEG compresses worst.

Can I still search the text afterwards?

No. The output is pixels, so text is no longer selectable, searchable or readable by screen readers. Keep the PDF if searchability matters, or run OCR on the images to recreate a text layer.

Does converting to images prevent copying?

It makes copying inconvenient, not impossible — OCR recovers the text readily. It does reliably make the document unreadable to anyone using assistive technology, which is a significant cost for a weak protection.

How do I get the photographs out of a PDF?

That is image extraction rather than page rendering. Extraction pulls out the embedded image objects at their original resolution; rendering a page and cropping gives a lower-quality copy with the page background included.

Why are the files so large?

Each page becomes a full-resolution bitmap. A 300 DPI A4 page is roughly 2480 × 3508 pixels. Use a lower resolution for screen purposes, and convert only the pages you actually need.
