Convert PNG to PDF
Add your PNG images (screenshots, diagrams, logos, scans) and get a clean PDF: one image per page, in the order you choose, in Letter, Legal, A4, A3, A5 or the image's own size. Images are embedded with no quality loss and transparency becomes a white background. Free, no sign-up, and your files are never uploaded.
- Lossless quality
- Many PNGs, one PDF
- Letter, A4 or actual size
- 100% private
100% private — Everything is processed directly in your browser: your files, voice, and image are never sent to Chatzam's servers.
How to convert a PNG to PDF
-
Add your PNGs
Drag one or more images into the box, tap “Browse”, or paste a screenshot with Ctrl+V.
-
Arrange and lay out
Change the order with the arrows (or by dragging pages in the preview), then pick the page size, orientation and margins.
-
Create the PDF
Tap “Create PDF”: the file downloads right away, one image per page, ready to send or print.
A PDF true to your images
No quality loss
Your PNGs are embedded as they are, without being recompressed to JPG: text in screenshots and lines in diagrams stay perfectly sharp.
Transparency handled
Transparent areas of a PNG become white (or the color of your choice) instead of showing up black or as a checkerboard.
Page preview
Each page is shown with its size, margins and image placement: you see the result before creating the PDF.
Nothing is uploaded
The PDF is built in your browser: your screenshots and personal documents never pass through a server.
Turn a PNG into a PDF in seconds
PDF is the format expected by government offices, schools, employers and most online forms. If your document is a PNG image (a screenshot, a receipt saved from a website, a diagram or a floor plan), this tool converts it to PDF with no software: add the image, choose the layout and download. You can also combine several PNGs into one multi-page PDF, in whatever order you like.
High-quality, lossless PNG to PDF
Many converters recompress images to JPG before putting them in the PDF: the letters in screenshots turn blurry and get surrounded by little smudges. Here, “Lossless” mode embeds the original PNG pixel for pixel. For a lighter file, for example to send by email, choose “Compact” mode: images are then saved as high-quality JPG. JPG photos added alongside your PNGs stay JPG in both modes. A PNG is still an image: the resulting PDF isn't vector-based and its text can't be selected; for that, run the PDF through our “OCR PDF” tool afterwards.
Page size, margins and transparency
Choose US Letter or Legal for documents to print or upload in North America, A4 elsewhere, A3 for a plan or a poster, A5 for a small format, or “Image size” for a page that matches the PNG's exact dimensions, with no white border. Automatic orientation sets each image to portrait or landscape based on its shape. Transparent areas of the PNG are filled with white by default, or with the color you choose, so the result looks the same in every PDF reader and when printed.
On PC, Mac, iPhone or Android, no app needed
The tool runs in your browser: Chrome, Edge, Firefox or Safari, on a computer or a phone. On iPhone, add your screenshots from Photos or Files; on Android, from the gallery. Your images are never uploaded. For other image formats, our “JPG to PDF” tool also accepts photos, and “PDF to PNG” goes the other way.
Frequently Asked Questions
How do I put several PNGs into one PDF?
Add all your images at once (or in several goes), arrange them with the arrows or by dragging pages in the preview, then tap “Create PDF”. Each image becomes a page of the same file.
Will my images lose quality?
Not in “Lossless” mode (the default): the PNG is embedded pixel for pixel. “Compact” mode shrinks the PDF by saving images as high-quality JPG.
Why does my transparent PNG turn black in other converters?
Some viewers display transparency badly. Here, transparent areas are filled with white (or the color you choose) before the PDF is created, so it looks the same everywhere, including on paper.
How do I make a page the exact size of my image?
Choose “Image size” as the page size and “None” for margins: the page is then exactly the size of the PNG, like a screenshot.
Will the text in my screenshot be selectable in the PDF?
No, a PNG is an image: the PDF contains it as is. To make the text selectable and searchable, run the PDF through our “OCR PDF” tool afterwards.
Is there a limit on the number or size of images?
There's no limit tied to an account. The only limit is your device's memory: hundreds of screenshots work fine on a computer; on an older phone, go in batches of a few dozen.
