Convert PNG to PDF
Up to 3 files at once, 100 with Pro. Mixed formats are fine.
PNG is what a screenshot or an exported diagram usually is. PDF is what people ask you to send. This puts one inside the other without touching the picture.
Screenshots end up needing to be PDFs surprisingly often. A support ticket wants evidence, an expenses system takes PDF and nothing else, a report has to include a chart you exported from a spreadsheet. The image itself is correct — it is only the container that is wrong, and the fix should not cost you anything.
It does not. A PDF is allowed to carry PNG data directly, so this conversion embeds your file exactly as it arrived rather than decoding and re-encoding it. Nothing is compressed a second time and no pixel changes. For a screenshot that is more important than it sounds: screenshots are full of small text, and small text is precisely what re-compression smudges first. A converter that quietly re-encodes gives you a PDF where the error message you were trying to show is slightly harder to read. This one does not.
Transparency survives, which sets this apart from converting a PNG to JPG. PDF understands an alpha channel, so a diagram exported without a background keeps it — it will appear over white when printed and over whatever is behind it when the PDF is placed into another document. If you wanted a solid background, add it before converting rather than after.
Page size is the setting most worth changing, depending on where the file is going. By default the PDF page is exactly the pixel dimensions of your image, so there is no border and no scaling — ideal for something that will be read on a screen or attached to a ticket. It is unpredictable on paper, though: a tall screenshot becomes a tall, narrow page that a printer will do something arbitrary with. If it is going to be printed, set A4 or Letter and the image is centred on a real sheet, scaled down to fit if it is too large and never scaled up.
The limitation to know about is text. A PNG of a document, a slide or a terminal window is a picture of words, not words. The PDF you get cannot be searched or selected, and a system that specifically requires machine-readable text will reject it. Where the original exists as something other than an image — a web page, a spreadsheet, a design file — exporting a PDF from that program directly gives you real text and a much smaller file. Screenshot to PDF is the right answer when the screenshot is the point, and the wrong one when it was a shortcut.
All of it happens in your browser. Nothing is uploaded, which is worth knowing when the screenshot contains an internal dashboard, a customer record or half your inbox.
How to convert
- Drop your PNG onto this page, or click to choose one.
- It becomes a PDF immediately, in your browser, with the image untouched.
- Download it — or set a page size first if it is going to be printed.
What to expect
- Quality
- Nothing is lost. The result holds exactly the same picture, text or data as the original.
- Where it runs
- This conversion runs inside your browser. Your file is never uploaded, and it works with the network disconnected.
Questions
- Are my PNG files uploaded anywhere?
- No. This conversion runs entirely inside your browser, so the file never leaves your device. You can confirm it yourself: open the network tab of your browser's developer tools and watch that nothing is sent while the file converts.
- Does the image lose any quality?
- None. A PDF can hold PNG data directly, so the image is embedded exactly as it is — not decoded, not re-compressed. A screenshot stays pixel-perfect, which matters when it is full of small text.
- What happens to a transparent background?
- It is kept. PDF understands transparency, so a diagram exported with no background stays transparent — which usually means it appears on white when printed and blends in when placed on a coloured page.
- Can I get several screenshots into one PDF?
- Not yet. Each file becomes its own PDF, and merging them is a PDF tool rather than a conversion. Drop a batch and take the results as a ZIP for now.
- Will it print at the right size?
- By default the page is exactly the size of your image in pixels, which is right for reading on screen and unpredictable on paper. If it is going to be printed, set the page size to A4 or Letter in the settings — the image is then centred and scaled down to fit with a margin.
- Can I select the text in the PDF?
- No. A screenshot is a picture of text rather than text, and this conversion does not read it. If you need selectable text, export a PDF from whatever produced the original — a browser, a document, a design tool — rather than screenshotting it.
