# PNG to PDF
|
||
|
|
|
||
|
|
Convert PNG images to PDF while preserving their full resolution. Each PNG becomes its own page, sized to match the original image dimensions. Transparency is handled automatically.

|
## How It Works
|
||
|
|
|
||
|
|
1. Click the upload area or drag and drop PNG files. You can select several at once.
|
||
|
|
2. Manage the file list -- remove unwanted files or add more.
|
||
|
|
3. Choose a **PDF Quality** level from the dropdown.
|
||
|
|
4. Click **Convert to PDF**. The output downloads as `from_jpgs.pdf`.
|
||
|
|
|
||
|
|
The tool uses pdf-lib to embed each image directly. If a PNG cannot be embedded natively (e.g., due to an unusual color profile), it falls back to re-rendering through a canvas as JPEG.
|
||
|
|
|
||
|
|
## Options
|
||
|
|
|
||
|
|
**PDF Quality** controls the compression applied before embedding:
|
||
|
|
|
||
|
|
- **High Quality** -- minimal compression, largest file size.
|
||
|
|
- **Medium Quality** (default) -- good balance of size and clarity.
|
||
|
|
- **Low Quality** -- maximum compression, smallest output.
|
||
|
|
|
||
|
|
## Use Cases
|
||
|
|
|
||
|
|
- Converting screenshots into a multi-page PDF for bug reports or documentation
|
||
|
|
- Packaging UI design exports into a single file for review
|
||
|
|
- Turning diagram exports (draw.io, Excalidraw) into a shareable PDF
|
||
|
|
- Assembling a set of chart images into a report
|
||
|
|
|
||
|
|
## Tips
|
||
|
|
|
||
|
|
- PNG files with transparency get a white background in the PDF. If you need a different background, edit the images beforehand.
|
||
|
|
- For screenshots and diagrams with sharp edges and text, High quality avoids JPEG compression artifacts. Medium or Low may convert to JPEG internally.
