Convert PDF to PNG: what to know
PNG is the format to choose when a PDF page must stay pixel-perfect: a diagram going into documentation, a slide reused in another deck, a page of a contract that will be annotated in an image editor, or a screenshot-quality copy of a table. This page renders each page in your browser, never uploads the PDF, and writes a losslessly optimised PNG per page.
How to convert PDF to PNG
Add your PDFs above; each shows a first-page preview and its page count. PNG is preselected. Choose 150 dpi for screens or 300 dpi for print, optionally limit the pages with a range such as 1, 4-6, and click Convert. Download the pages you need or take the whole batch as a ZIP. Results can also be sent straight to the compressor, cropper or converter without downloading.
Why PNG for text, tables and diagrams
JPG compression smears the sharp edges of letters and thin lines into faint halos, which is visible on a page of text at any quality setting. PNG stores the rendered pixels exactly, so a page of text or a wireframe is as crisp as the PDF itself. The cost is size: a 150 dpi A4 text page is typically 100–300 KB as an optimised PNG, and pages with photographs can be several megabytes, where JPG would be a tenth of that.
Toolkitta runs every PNG through a lossless optimiser, so the files are as small as PNG can make them without changing a pixel. Pages are rendered on an opaque white background; PDF pages do not have transparency to keep.
Resolution guide
72 dpi gives a page at its nominal size — around 595 × 842 pixels for A4 — which is fine for a thumbnail or a quick reference. 150 dpi (about 1240 × 1754) is the default and looks sharp on laptop and phone screens, including high-density displays when the image is shown at half size. 300 dpi (about 2480 × 3508) matches print resolution and is the right choice when the PNG will be printed or zoomed into. Pages larger than 40 megapixels at the chosen setting are rendered at a lower dpi automatically, and the file details say so.
Limits and things to know
Up to 20 PDFs of 50 MB each per batch and 300 rendered pages per run; use a page range for long documents. Password-protected files ask for their password on the row and open on your device. Vector content is rasterised at the chosen resolution — there is no way to keep it as vectors inside a PNG — and form fields and annotations are drawn as they appear.
Questions about PDF to PNG
- Is the PDF uploaded?
- No. Pages are rendered by a PDF engine running in your browser; nothing leaves your device.
- Is the PNG lossless?
- Yes. The rendered page is stored exactly, then losslessly optimised to keep the file as small as possible.
- Can I choose the pages?
- Yes. Leave Pages empty for every page or enter a range like 3-5, 8.
- What if I need smaller files?
- Choose JPG instead, lower the dpi, or send the PNGs to the compressor afterwards.
