Convert PNG to PDF
- 100 % in the browser
- No server uploads
- Free forever
To convert PNG to PDF, drop your images into the box above, set the order and tap “Create PDF”. Each PNG becomes one page and is embedded losslessly, so text and lines stay as sharp as in the original. You choose what happens to transparent areas: white, black or keep them transparent. Everything runs in your browser, nothing is uploaded. Free, no account, no limit.
How to convert PNG to PDF
Add your PNG files
Drag your PNGs into the box above or tap “Choose files”. Screenshots, graphics, logos and scans all work, and you can mix in JPGs. Pick as many as you like.
Sort and check
Drag the images into the order you want or use the arrows. Transparent PNGs show a checkerboard in the preview so you can see which ones have see-through areas.
Set page and background
Choose A4, Letter or “Fit image”, the orientation and margin. Under “Background” you decide what transparent areas become: white, black or kept transparent. “Embedding” stays on lossless unless you need a smaller file.
Create and download
Tap “Create PDF”, then “Download PDF”. The file is named after your image, or “images-merged.pdf” for several, and lands in your downloads folder.
When do you need this?
Screenshots as one document
A chat history, a sequence of error messages or a step-by-step guide: screenshots usually arrive as PNG. As one PDF they are easy to send, file and read in order, and every letter stays crisp.
Charts and diagrams for a handout
Charts exported from spreadsheets or design tools are PNGs with thin lines and small labels. Lossless embedding keeps them legible, which JPG compression would blur.
A logo or graphic for the print shop
Print shops often ask for a PDF. Put your PNG logo on a page, decide whether the transparent area should be white or stay transparent, and send the PDF instead of a loose image.
Drawings and notes from a tablet
Note and drawing apps export pages as PNG. Combine them into one PDF to hand in or archive them, with the page order you choose.
PNG vs. PDF: what's the difference?
PNG is a lossless image format: every pixel is stored exactly, and it can hold transparent areas. That makes it the standard for screenshots, graphics and logos. PDF is a document format with fixed pages that looks the same everywhere and can hold any number of pages.
Converting a PNG to PDF keeps the pixels unchanged. What changes is the packaging: one file, fixed pages, ready to print and share. If you only need a single image for the web or a chat, PNG is the better choice; for documents, PDF.
| Feature | PNG | |
|---|---|---|
| Content | One image, pixels stored losslessly | Any number of pages in one file |
| Transparency | Yes, transparent areas possible | Possible, but shown as white by most viewers |
| Text and fine lines | Razor sharp, no compression artifacts | Just as sharp when embedded losslessly |
| Typical use | Screenshots, logos, graphics, web | Documents, forms, handouts, printing |
| Printing | Size and position set by hand | Fixed page size, prints as laid out |
| File size | Small for graphics, large for photos | About the size of the images inside |
Good to know
- Lossless by default: Your PNGs are embedded in the PDF without any loss. The PDF uses the same kind of compression as PNG itself, so every pixel stays exactly as it was. You can check: zoom far into the PDF and the text stays clean.
- Transparent areas: “White” and “Black” fill transparent areas with that color. “Transparent” stores the transparency in the PDF. Most viewers then show the page color, which is usually white; dark-mode viewers may show dark.
- Smaller file: PNG photos can be several MB each. Switch “Embedding” to “Smaller” and the images are re-encoded as JPG inside the PDF. Fine for photos, not for screenshots with small text.
- Text in the PDF: Text in your screenshots stays part of the image. It can’t be selected or searched in the PDF, and the PDF doesn’t add any pixels your PNG doesn’t have.
Tip: For screenshots, choose “Fit image” and “None” as the margin. Each page is then exactly the size of the screenshot, with no white border.
Quick check: Open the finished PDF and zoom to 400 %. Lossless embedding means edges stay crisp, with none of the blocky halo you get around JPG text.
Troubleshooting
My white logo disappeared in the PDF. Why?
A white logo on a transparent background becomes invisible on a white page. Set “Background” to “Black” and create the PDF again. The logo then sits on a black page.
The PDF is much bigger than I expected. What can I do?
PNG stores photos inefficiently, and the PDF keeps every pixel. Switch “Embedding” to “Smaller”: photos then take a fraction of the space. For screenshots and graphics, keep “Lossless”, they are small anyway.
The image looks blurry when I zoom in.
The PDF contains exactly the pixels of your PNG, no more. A small screenshot of 400 × 300 pixels stays small. Take the screenshot at a higher resolution or use a larger original, then convert again.
Transparent areas appear black in one app.
A few apps draw a dark background behind transparent PDF images. If the PDF is meant for others, choose “White” as the background. The result then looks the same everywhere.
Why does nothing happen when I add a file?
The file is probably not a PNG or JPG. This tool doesn’t take WebP images from the web, HEIC photos from an iPhone or SVG graphics. For those, use Image to PDF: it accepts these formats directly, even mixed with PNGs.
Is my file uploaded?
No. The conversion runs entirely in your browser, on your own device. The file itself is never sent to a server, never stored and never seen by us. Close the tab and it is gone from memory.
You can check this yourself: open your browser's developer tools (F12), switch to the “Network” tab and start the conversion. Your file does not show up as an upload. What you may see are page resources and, if you agreed to them, ads or statistics.
FAQ
Is converting PNG to PDF on Filemanta free?
Yes, completely. There is no daily limit, no cap on the number of images, no watermark and no subscription. You don't need an account either.
Are my PNG files uploaded?
No. Your images are turned into a PDF on your own device, in the browser, and never sent to a server. That matters for screenshots of chats, bank statements or documents.
What happens to transparent areas?
You decide. Choose “White” or “Black” to fill them with that color, or “Transparent” to store the transparency in the PDF. Most PDF viewers show kept transparency as white, because the page itself is white.
Will I lose quality?
No. PNGs are embedded losslessly, so every pixel stays exactly as it was. Text, lines and edges in the PDF are as sharp as in the original. Only if you choose “Smaller” are the images recompressed.
Can I combine several PNGs into one PDF?
Yes. Add all your PNG files, put them in order and tap “Create PDF”. Each image becomes its own page in a single PDF. There is no limit on the number of files.
Can I convert screenshots to PDF on my phone?
Yes. On iPhone and Android, pick the screenshots from your photos, set the order and create the PDF. Save it to Files or your downloads folder and share it from there. No app needed.
Can I mix PNG and JPG files?
Yes. Add both in one go. PNGs are embedded losslessly, JPGs unchanged. Each image becomes a page, in the order you set.
What page size should I pick?
For documents, A4 or Letter. For screenshots and graphics, “Fit image” makes each page exactly as large as the image, without white borders. You can combine that with any margin.
Can I turn the PDF back into PNG files?
Yes, with Filemanta's PDF to PNG tool. It saves every page as a lossless PNG, with a transparent background if you want, also without uploading anything to a server.
