Convert PNG images to PDF

About this tool

Build a real PDF from RGB/RGBA PNG images, one image per page in your chosen order.

Supported input

PNG

Output format

PDF

Batch size

Up to 5 files; format and combined limits below still apply.

How it works

1. Add RGB/RGBA PNG files in Input. Review each thumbnail and its validation status.
2. Order and select the pages in Input, then choose paper size and embedded-image quality.
3. Create the selected files. Compare original and result, then download an individual file or ZIP. Changing settings marks older results out of date.

Supported files and limits

Up to 5 files, 10 MiB each and 25 MiB combined. Each image must fit within 8192 pixels per side and 20 million pixels; a batch is limited to 40 million input pixels. Output is limited to 20 MiB per file and 50 MiB combined. One isolated image job runs at a time, with a 30-second timeout and cancellation.

A practical example

Turn a supported PNG diagram into a PDF page for sharing with a recipient who expects PDF. Select page sizing and check that the diagram remains readable.

Troubleshooting this tool

The diagram is flattened into an embedded JPG image. Transparent areas use the selected background; this does not preserve vector lines, editable text or alpha.

PNG input must be non-interlaced, 8-bit RGB or RGBA. Animated PNG, EXIF, ICC profiles and compressed/international text metadata are rejected before decoding.

Check the actual export

Select and order 1–5 images in Input. Choose A4, Letter or image-size pages, then create one multipage PDF. Images are embedded as JPG and transparency is flattened onto your chosen colour; this is not a lossless archive or searchable/OCR document. Inspect downloaded dimensions, transparency and fine edges before replacing an original. Browser encoders differ; a quality setting is not a universal fidelity score, and file size may increase.

Files stay in your browser

No file bytes are uploaded. Ordinary work stays in memory. Choosing a “Continue” action saves that result in this browser for up to 30 minutes, so another compatible working tool can use the actual output. Saved workflows are limited to 50 MiB and 20 files; clear them in Output. Expired entries are removed on later tool visits. Clearing references is not a secure-erasure promise.

If a file fails

Check its actual format and the restrictions above. Renaming a file does not convert it. A failed file does not erase successful batch results. If processing times out, cancel and try fewer or smaller files. A current browser with worker canvas support is required.

Before you use the download

• Open every PDF page and confirm image order, paper fit and readable detail.
• Picture pages do not contain recognized text; check the selected transparency background and embedded-image quality.

Tools that accept this output

These links use this tool's default output format, subject to each next tool's supported variants and limits. If you change the export format, use Continue in Output to see compatible actions for the actual result. Opening a link below starts another tool without transferring a file.

• Merge PDF files — Join simple PDF documents in your chosen file order, without rasterizing their pages.
• Rotate PDF pages — Rotate all or selected pages of a simple PDF by 90, 180 or 270 degrees clockwise.
• Split PDF into parts — Split a simple PDF into equal-sized page groups and download the actual PDF parts in a ZIP.
