Why JPG Isn't Enough for PDF Preview Images

You need crisp PDF previews with transparent backgrounds for overlays, but JPG compression creates artifacts. Manual PNG exports take forever, and existing tools don't support transparency.

JPG Compression Artifacts

JPG creates visible artifacts around text and sharp edges—making your previews look unprofessional.

No Transparency Support

You need transparent backgrounds for overlays and watermarks, but most tools only output opaque images.

Manual Export Hell

You're manually exporting PNGs for every PDF upload—wasting hours and slowing down your workflow.

FAQ: PDF to PNG Conversion

What's the difference between PNG and JPG output? ▼
PNG is lossless and supports transparency, while JPG is compressed and smaller. Use PNG for proofs and overlays, JPG for web thumbnails.

Yes. Set transparent: true in the API request to enable alpha channel. Perfect for overlays and watermarks.
What resolution should I use? ▼
Use 72-150 DPI for web display and 300 DPI for print proofing. Higher DPI creates larger files but sharper images.
