Real alpha channel · No JPG-in-PNG cheat · Up to 600 DPI
PDF to PNG with a transparent background — really transparent.
Most converters silently bake a white rectangle behind your logo. Drop the PNG on a dark slide and the seam shows. This one renders to an RGBA canvas, encodes with the real PNG encoder, and your alpha channel survives the round-trip.Real PNG. Real transparency. No white background baked in.

Browser-native canvas toBlob() encoder. Bit-preserving. No watermark, no signup, no Pro gate.
Transparency guarantees — what survives the round-trip.
Five properties you lose with a typical converter. All preserved here.
Alpha channel
Preserved
Rendered to RGBA canvas with alpha enabled. Transparent stays transparent.
Resolution
600DPI
Up to 4× density for retina, print, or scaled slide-deck embeds.
Encoding
Bit-preserving
Lossless PNG, not a downgraded JPG rewrapped in a PNG container.
No JPG-in-PNG
Guaranteed
Browser-native toBlob("image/png"). Not a cheat, not a rename.
Licensing
Commercial OK
No watermark, no attribution. Your rights on the PDF carry over.
Built around the alpha channel, not despite it.
Tuned for logos, overlays, and design assets where "transparent" is a requirement, not a nice-to-have.
Real PNG encoder — the browser's canvas.toBlob(), not a repackaged JPG.
We render each PDF page to an HTML canvas with alpha:true, then export via canvas.toBlob("image/png"). That's the same encoder Chrome and Firefox use for every PNG screenshot they produce. Lossless. Real alpha. Standards-compliant. No rewrapped JPG nonsense.
RGBA 8-bit
true alpha channel on every pixel, not a 1-bit mask.
Alpha survives the round-trip.
Drop the PDF → get a PNG → drop the PNG on a dark background. The logo floats. No seam, no halo, no white rectangle. Test it in Figma, Keynote, or over a CSS checkerboard.
JPG-in-PNG trick: not here.
Some tools silently encode as JPG (no alpha) and rename to .png. Spot it by file size + ImageMagick
identify -verbose. We use the browser's actual PNG encoder — sibling page: presentation-ready images.Your logos never leave the browser.
Brand assets, client work, NDA-covered designs stay local. See no-upload PNG.

Same goal: convert a logo PDF to a PNG that keeps its transparent background. Watch what happens.

1
Drop your PDF
Loads into browser memory. No upload. The render happens on your CPU.
2
Alpha auto-detects
The canvas opens with alpha:true by default. Pick a DPI (72–600), confirm page range, and the renderer preserves every transparent pixel from the PDF.
3
Download a real PNG
Browser's canvas.toBlob("image/png") produces a standards-compliant PNG with 8-bit alpha. Open in Figma, Photoshop, Keynote — transparency is there.

Frequently asked questions
Does this tool actually preserve transparency in the PNG?
Yes. We render to an HTML canvas with alpha enabled, then export via the browser-native toBlob() PNG encoder. The output PNG carries a real alpha channel — areas that were transparent in the source PDF stay transparent in the PNG. Drop the file into Photoshop, Figma, Keynote, or a web page and the checkerboard shows through.
Why do other converters bake a white background into the PNG?
Two common reasons: (1) they render onto a solid white canvas and never switch alpha on, so every "transparent" pixel becomes opaque white, or (2) they produce a JPG internally and rename it .png — a classic JPG-in-PNG cheat. Both destroy transparency. This tool avoids both paths by rendering directly to an RGBA canvas and encoding with the real PNG encoder.
What's the "JPG-in-PNG cheat"?
Some converters compress the image as JPG (which has no alpha channel) then wrap it in a PNG container to keep the .png extension. The file is PNG-shaped but carries JPG-style lossy compression and no real transparency. You can spot it by file size (suspiciously small for PNG) or by inspecting with ImageMagick's
identify -verbose. This tool never does that — the encoder is the browser's real PNG implementation.Can I convert a PDF logo to a transparent PNG for free?
Yes. Every conversion is free, every DPI preset up to 600, no watermark, no daily cap, no account. See also the general free PDF to PNG converter if you don't specifically need the transparency-first workflow.
What DPI should I pick for a logo PNG?
For web use at normal size, 150 DPI is plenty. For retina display or larger web embeds, 300 DPI. For a logo that will be scaled up in presentations or print artwork, use 600 DPI — it renders 4× more pixels and survives aggressive resizing. All presets preserve transparency.
Does the tool work with multi-page PDFs?
Yes — each page exports as a separately numbered PNG (page-01.png, page-02.png…) with independent transparency. Also works on single-page logo PDFs. Batch download as ZIP or individually.
Is the PDF uploaded when I convert it?
No. Everything runs in your browser. DevTools → Network shows zero upload requests. Same privacy model as the PDF to PNG without upload page — designed for logos, brand assets, and NDA-covered designs.
Will the transparent PNG work in PowerPoint, Keynote, and Google Slides?
Yes. PNG with alpha is the universal standard across slide decks. Drop the PNG onto a slide and the background shows through — no white rectangle. For batch slide exports, also see PDF for presentations.
Can I use the PNG commercially — in products, marketing, client work?
Yes, subject to the rights you already hold on the source PDF. This tool adds no watermark, no licensing, no attribution requirement. If you own the PDF (your logo, your design), you own the PNG you get out. If the PDF is third-party, the same copyright rules apply as always.
What if the PDF doesn't have a transparent background in the first place?
Then the exported PNG will have the PDF's native background — usually white or the page color. Transparency can't be invented from opaque content. If you need to cut out a logo from a flat white background, open the PNG in Photoshop or an online background-remover after conversion.
Can I compare my output with what other tools produce?
Yes, that's the point of the race section above. Open both PNGs side-by-side in Photoshop → view the alpha channel, or drop both over a checkerboard background in a web browser. Ours has a real alpha; the typical converter's usually doesn't.
Does PNG support CMYK for print?
PNG is sRGB by spec. For print work, use the print-ready JPG converter at 300 DPI, or ask your printer whether they want a TIFF. PNG's strength is transparency for web, UI, and slide-deck overlays — not press-ready color.
How big are the output files?
PNG is lossless so files are larger than JPG. A 300 DPI A4 page with transparency is roughly 2–8 MB depending on content. Large logos with lots of smooth gradients can be 10+ MB. For web, run the PNG through a compressor like pngquant after export if size matters.
Can I convert password-protected PDFs?
Yes, with the password. The decrypt happens locally so neither the password nor the PDF leaves your browser.
How does this relate to the general PDF to PNG converter?
This page specifically guarantees transparency preservation for logo / overlay workflows. The general PDF to PNG online converter covers the broader case. Same underlying encoder, different defaults.
Real transparency. Real PNG encoder. Local render.
Drop your logo PDF, keep the alpha, drop the result anywhere. No upload, no white rectangle, no JPG-in-PNG cheat, no Pro gate.
