PNG & PDF: How the Conversion Works

A quick primer on the two formats and what actually happens when you turn images into a PDF here.

🖼️
1996
PNG launched in 1996 as a free, lossless, patent-unencumbered alternative to GIF.
📄
1993
PDF was created by Adobe in 1993 and is now the ISO 32000 standard for fixed-layout documents.
🎨
Alpha
PNG supports full transparency, which is flattened onto the page background when placed in a PDF.
📐
1 page
Each image becomes one PDF page, scaled and aligned to your chosen size and margin.
🔗
Merge
Many images can be combined into one multi-page PDF — perfect for documents and portfolios.
Universal
The output PDF opens everywhere — Acrobat, Preview, browsers and every mobile reader.

PNG (Portable Network Graphics) is a lossless raster image format from 1996, prized for sharp edges and full transparency, while PDF (Portable Document Format) is Adobe's 1993 fixed-layout document standard, now ISO 32000. Putting images into a PDF is a great way to bundle many pictures into one shareable, printable, universally-readable file. This tool uses the open-source jsPDF library to build a genuine PDF entirely in your browser: each image is placed on its own page at the page size, orientation, fit mode, margin and alignment you choose. You can merge everything into a single multi-page PDF, or output one PDF per image bundled into a ZIP via JSZip. Because PNG transparency can't be preserved as a transparent page, transparent areas are composited onto the page background when rendered.

Every Setting Explained

A complete reference for every control in the converter — what it does, what to pick, and how it affects the output PDF.

📄Page Size

The paper size of each page

A4, Letter, A3 and A5 are standard paper sizes for printing and sharing. Fit to Image Size makes each page exactly the pixel dimensions of its image — ideal for portfolios and comics where you want no border or paper letterboxing.

🔄Orientation

Portrait, landscape or auto

Portrait and Landscape fix every page one way. Auto (per image) picks the best orientation for each image individually, so wide images get landscape pages and tall ones get portrait — great for mixed batches.

🖼️Image Fit

How the image sits on the page

Fit keeps the full image visible and preserves aspect ratio. Fill crops to fill the whole content area. Stretch distorts the image to fill the page exactly. Original Size places the image at its natural size (capped to the page).

📐Margin

White space around the image

From None (0mm) for edge-to-edge images, up to Extra (25mm) for a generous border. Medium (10mm) is a balanced default for printed documents. Margins don't apply when Image Fit is set to Stretch.

📦Output Mode

One PDF or many

Merge into One PDF combines every image into a single multi-page document. Separate PDF per Image creates one PDF for each image and delivers them bundled in a ZIP. Use merge for documents, separate for individual files.

📍Image Alignment

Where the image sits

Center places the image in the middle of the content area. Top Left and Top Right anchor it to that corner. Alignment is most visible when the image doesn't fill the whole page (Fit or Original modes).

📋Filename

What the download is called

Sets the output name. In merge mode you get filename.pdf; in separate mode you get filename_pdfs.zip (each PDF inside is named after its source image). Pick something descriptive so it's easy to find later.

↕️Drag & Arrows

Reordering pages

Drag any image card to a new position, or use the ◀ ▶ arrows for single-step moves. The order shown is exactly the page order in your PDF. The ✕ button removes an image; Add More appends new ones.

Best Practices for
Better PDFs

A few small choices make your converted PDF cleaner, sharper and better suited to its purpose.

01

Use "Fit to Image" for borderless

For portfolios, comics and photo books, Fit to Image with 0 margin gives edge-to-edge pages with no paper letterboxing.

02

Use A4 + Fit for documents

For scans and paperwork that will be printed, A4 (or Letter) with Fit and a 10mm margin gives a clean, standard page.

03

Set order before downloading

Drag cards or use the arrows to get the exact page order first — it's the order they'll appear in the PDF.

04

Auto orientation for mixed batches

If your images are a mix of wide and tall, choose Auto orientation so each page rotates to fit its image best.

05

Avoid Stretch unless intentional

Stretch distorts images to fill the page. Use Fit to keep proportions correct unless you specifically want full-bleed distortion.

06

Separate mode for individual files

Need one PDF per image? Switch to Separate mode and you'll get a ZIP with each image as its own named PDF.

07

Start from high-res images

The PDF is only as sharp as the source. Use full-resolution PNGs for crisp printing, not small thumbnails.

08

Remember transparency flattens

PNG transparency can't stay transparent in a PDF page — see-through areas composite onto the page background.

09

Preview before converting

Click thumbnails to check each image at full size. It's faster to catch a wrong or rotated image now.

10

Name the file clearly

A descriptive filename (like "expenses-march") makes the download easy to find and forward later.

11

Convert big batches on desktop

Dozens of high-res images use a lot of memory. A desktop browser handles large batches far better than a phone.

12

Mix formats freely

You can drop in JPG, WebP, GIF and BMP alongside PNGs — they'll all combine into the same PDF in one pass.

Why This Tool Is Different
(and Safer)

Most online image-to-PDF converters upload your files to a server. This one runs entirely in your browser — your images never leave your device.

🔒 100% Client-Side Conversion

Every step — reading your images, laying them onto pages, building the PDF, bundling the ZIP, saving the file — runs in your browser's own JavaScript engine. No image content and no PDF output is ever transmitted over the network.

No File UploadsYour images stay on your device. The browser's Network tab will confirm: zero outbound requests with file data.
No Account RequiredNo sign-up, no email, no tracking cookies. Open the page, drop images, get a PDF.
No File RetentionBecause the server never sees the files, there's literally nothing for us to store, leak or sell.
Works OfflineOnce the page is loaded, switch off Wi-Fi and the converter still runs end-to-end.
Open-Source EnginesBuilt on jsPDF and JSZip — open-source libraries you can audit on GitHub any time.
Document-SafeSensitive scans, IDs and contracts never leave your machine — ideal for private paperwork.

PNG to PDF — Common Questions

Everything you need to know about converting PNG images to PDF — covering merging, formats, layout and privacy.

Is this PNG to PDF converter really free?
Yes, 100% free with no hidden fees, no subscription, and no signup required. Use it as many times as you like, with as many images as you need.
Are my images uploaded to a server?
No. This tool runs entirely in your browser. Your PNG images are never sent to any server — all processing and PDF generation happens locally on your own device.
Can I convert multiple PNG images into one PDF?
Yes. Upload as many PNG images as you need, arrange them in order by dragging, and select "Merge into One PDF". Each image becomes one page of the PDF.
Does this work with JPG and other formats too?
Yes. While optimized for PNG, this tool also accepts JPG, WebP, GIF, BMP, and all other common image formats your browser supports.
What does "Fit to Image Size" page size mean?
When set to "Fit to Image Size", each PDF page is created at exactly the pixel dimensions of each PNG image, rather than a standard paper size like A4 or Letter.
Does this tool add a watermark to my PDF?
No. Absolutely no watermark is ever added to your downloaded PDF files. Your output is completely clean and ready for professional or personal use.
How do I reorder the pages?
Drag any image card to a new position, or use the ◀ ▶ arrows on each card for single-step moves. The order shown is exactly the page order in your PDF.
What's the difference between merge and separate mode?
Merge combines all images into one multi-page PDF. Separate creates one PDF per image and delivers them all in a single ZIP download.
Is PNG transparency preserved?
PDF pages aren't transparent, so see-through areas of a PNG are composited onto the page background (white by default) when placed in the PDF.
Which fit mode should I use?
Fit keeps the whole image visible with correct proportions — the safe default. Fill crops to fill the page, Stretch distorts to fill, and Original uses the image's natural size.
Is there a limit on how many images?
No artificial limit — only your device's memory. Desktop browsers handle large batches well; mobile devices are more constrained for many high-res images.
Can I add more images after uploading?
Yes. Use the "Add more images" zone below the list to append new images without losing your current order or settings.
Does it work offline?
Yes. Once the page and its libraries have loaded, you can disconnect from the internet and the converter still works end to end.
Will my images lose quality?
Images are placed into the PDF at their resolution. There's no aggressive re-compression, so quality is preserved as faithfully as the PDF allows.
Can I choose portrait or landscape?
Yes. Pick Portrait, Landscape, or Auto — which chooses the best orientation for each image individually based on its shape.
What filename will my download have?
In merge mode it's your chosen name plus .pdf. In separate mode it's your name plus _pdfs.zip, with each PDF inside named after its source image.
Does it work on mobile?
Yes. The interface is fully responsive and conversion runs in mobile browsers. For very large batches, a desktop browser handles memory better.
Can I remove an image before converting?
Yes. Click the ✕ button on any image card to remove just that image, or Clear All to start over.
Is my data really private?
Yes. Nothing is uploaded. You can verify in your browser's developer tools that no file data leaves your device during conversion.
Is there a daily limit?
No. Convert as many images to PDF as you want, as often as you want. There's no quota, no rate limit, and no premium tier.
