How to Convert PNG to PDF Online (Keep Transparency & Quality)
Need to turn PNG images into a professional PDF document? Learn how to convert with transparency support, batch upload, and drag-and-drop reordering.
You took screenshots of an error log, saved design mockups as PNG files, or exported charts from a data tool. Now you need to compile them into a single, shareable PDF document.
Our free PNG to PDF tool converts PNG images into high-quality PDF Files — and unlike JPG conversion, it preserves transparency for images with transparent backgrounds.
Why PNG to PDF?
- Transparency Support: PNG is the only common image format that supports transparency. Our converter preserves this when creating the PDF.
- Lossless Quality: PNG is lossless — no compression artifacts. Your images go into the PDF at their original quality.
- Batch Upload: Upload up to 50 PNG files at once and combine them into a multi-page document.
How to Convert
- Upload: Go to the PNG to PDF tool and drag your images in. Select up to 50 files at once.
- Organize: Drag-and-drop thumbnails to reorder your images. Rotate any images that need fixing.
- Convert: Click "Convert." Each image becomes a page, or merge all into one multi-page PDF.
- Download: Save your PDF.
Common Use Cases
- Designers: Compile mockups and wireframes into a review document.
- Developers: Bundle screenshots of bugs, error logs, or UI states for a report.
- Students: Convert diagram exports and chart screenshots into assignment submissions.
- Marketers: Package social media graphics into a brand asset PDF.
