PNG is the format to reach for when a page is dominated by sharp text, flat colour fields, charts, or line art — anything where crisp edges matter more than file size. Unlike JPG, PNG is lossless, so a diagram exported to PNG has no compression haloes around its strokes and a logo keeps perfectly clean boundaries. This converter renders each page of your PDF to a high-resolution PNG at 150 DPI, preserving every hairline rule and font edge.
Choose PNG over JPG when you plan to mark up a page, when it contains screenshots or UI mock-ups, or when it will be placed on a coloured background and you want clean anti-aliasing. For photo-heavy or scanned pages, JPG will give you a much smaller file with no visible difference.
When PNG beats JPG for documents
PNG shines on the kinds of pages JPG handles worst: solid colour backgrounds, fine black text on white, vector charts, and screenshots. JPG's lossy compression introduces faint 'mosquito noise' around high-contrast edges, which is exactly where document text lives. PNG stores those edges exactly. The trade-off is size — a PNG page is often several times larger than the equivalent JPG — so reserve it for pages where edge fidelity genuinely matters.
Transparency and overlays
Because PNG supports an alpha channel, it is the natural choice when you intend to composite a page over other artwork, build a watermark, or place a cut-out element into a design. While a standard PDF page renders on a white background, exporting to PNG keeps your options open for downstream editing in tools like Photoshop, Figma, or GIMP.
