About converting PNG to PDF
PNG images go into the PDF with their pixels unchanged. Transparent areas stay transparent in the PDF, showing the white page underneath. Images with lots of text or lines, such as screenshots and diagrams, keep sharp edges. If you set "Max long side", images are scaled down to that size and re-encoded.
Use "Move up" and "Move down" in the list to change the order. For the paper, choose "A4", "US Letter" or "Fit to image". "Fit to image" makes a page for each image, sized to the image plus the margins. With the margins set to "None", each page has the same aspect ratio as its image.
Frequently asked questions
Are my images sent to a server?
No. Reading the images and creating the PDF all happen in the browser on your device. Statistics that help us fix bugs (the range of image counts, ranges of how many images were inserted as they are or converted, error types and so on) are sent to this site's server. They do not include the content of the images or file names. You can turn the statistics off with the "Send processing statistics" switch at the bottom of the page.
How many images can I combine?
Up to 500 images at a time. With many images, depending on your device's memory, it may take a while or fail. In that case, make several PDFs and combine them with "Merge PDF".
Does the text stored in PNG files stay in the PDF?
No. Text stored in PNG files (such as the name of the app that created them) is not put into the PDF.
Can I also combine JPG or HEIC images?
Not on this page. This page accepts only PNG files. If you have JPG, HEIC, WebP or other images too, use "Image to PDF".
Help us improve the service
If a conversion fails, sending us the circumstances helps us track down the cause. Knowing which devices and formats fail most often, and how long processing takes, lets us revise the supported formats and fix the bugs behind them. If you don't mind, leaving this on is a real help.
What is sent
- The tool you used and the settings you chose (output format, quality, etc.)
- Your device specs (GPU, memory, core count)
- The input format with a rough size
- How many files succeeded or failed and how long it took
- The error type and details when something fails
What is never sent
- The files themselves and file names
- Text, subtitles or prompts you add to a video
- The text to be read aloud, voice descriptions, the pronunciation dictionary and saved voices
- The text in PDFs, the text you rewrote or redacted, passwords, font names and the page ranges you enter

The data goes only to this site's own server, never to a third-party service.
Details sent by specific tools (counts, times, kinds and yes/no only)
In addition to “What is sent”, text to speech and the PDF tools send the following details.
- PDF tools (all)This tool
- The page count range, whether editing is restricted, whether a permissions password was entered, and whether the PDF is signed or encrypted.
- PDF page operations and conversion between images and PDFThis tool
- The numbers of inputs and outputs, of pages rotated, deleted, duplicated or moved, of images inserted as they are, converted, in HEIC format or with corrected orientation, and of pages rendered at a lower resolution (all as ranges), whether the original was updated in place or a new document was created, and whether the original protection was reapplied, form fields were written into the page and bookmarks were added back.
- Text to speech
- The approximate number of characters and sentences, how many parts the text was generated in, and how long the AI model took to load.
- PDF text editing and redaction
- The numbers of rewrites, deletions, white-outs and redactions, the number of rewritten characters by source (original font or fallback font, the latter as a range) and the fallback typeface, the kinds of reasons why lines cannot be edited, and the number of pages turned into images by redaction and the reasons.
- PDF compression
- The numbers of inputs and outputs, of images downsized, not downsized and black-and-white, of downsized images whose transparency was also downsized, that stayed lossless or that were converted from CMYK to RGB, and how many times the file was compressed (all as ranges), the kinds of reasons images were not downsized, whether the target size was met and the kind of reason it was not met, the range of how much smaller the file got, whether the original protection was reapplied, and whether the original PDF was returned unchanged.
- PDF cropping and page numbers
- The numbers of inputs and outputs and of pages cropped, numbered or with their margins reduced (all as ranges), how the margins were set, how the pages to crop or number were chosen, the number format and position, the range of the starting number, that the original was updated in place, and whether the original protection was reapplied.
