Your files stay private
This PNG converter runs entirely in your browser. When you drop a file, it stays on your device—we never upload it to our servers, store a copy, or open it on our side. We cannot see what is inside your PNG, and refreshing or closing the page clears everything from memory instantly. No account is required to convert.
Note: like most websites, we may use cookies for ads and analytics on public pages. That is separate from your document—those scripts never receive your file contents.
What is PNG?
PNG is the format people use for screenshots, UI exports, diagrams, and graphics that need sharp edges or transparency. It stores pixels losslessly, so text stays crisp and a transparent background can stay transparent. That makes PNG awkward for some paperwork: a folder of screenshots is several files, and many school, government, and client portals only accept PDF. A PNG also does not describe page size or print order the way a document does.
What is PDF?
PDF is the standard for submitting paperwork, archiving a packet, and sharing print-ready pages. It preserves page order, embeds images, and opens the same way on phones and desktops. Unlike a bare PNG, a PDF can hold several screenshots in one attachment. Recipients see a document instead of a pile of image files, and forwarding it does not invite another app to recompress the pictures.
Why convert PNG to PDF
Convert PNG to PDF when a portal rejects images, when you need several screenshots in one file, or when a client asks for a PDF of a diagram or signed form. Students package homework screenshots. Designers send proof sheets. Office workers turn annotated captures into a single attachment. Creating the PDF in-browser keeps IDs, invoices, and internal screens off an upload server when privacy matters. Practical notes for PNG to PDF: treat PNG as your working source whenever you still need to edit, and treat PDF as the distribution format you hand to other people or upload into picky systems. Before you convert, confirm you are allowed to transform the file—especially for ebooks, photos of IDs, and client work covered by an NDA. After conversion, open the PDF output once on the same device you will use to share it; catch rotation, cropping, or missing pages early. If something looks wrong, revisit the source PNG: password locks, rare codecs, animated frames, or scanned pages without OCR explain most failures. For repeat jobs, keep a small checklist—file size under the free limit, orientation fixed, sensitive metadata removed, and a clear filename with the PDF extension. This png to pdf converter flow is meant for everyday private conversions in the browser, not for guaranteed print-shop color management or courtroom-grade forensics. When you outgrow the free daily allowance, Pro simply raises limits; it does not change the browser-local privacy model for this tool. Finally, prefer descriptive downloads such as “invoice-march.pdf” over generic names so you can find the right PDF later without reopening every file. If you convert the same PNG repeatedly while iterating on design or copy, keep a dated folder of PDF outputs so you can roll back when a stakeholder prefers an earlier version. Small habits like these matter more than chasing mythical “perfect” conversion settings for everyday PNG to PDF jobs. When in doubt, convert a sample page or image first, then run the full batch once you like the result.
Tips for best results
- Crop extra desktop chrome before converting so each page focuses on the content.
- Transparent areas sit on the white PDF page. Flatten onto a color first if you need a different background.
- Very large screenshots make heavy PDFs—resize for email if needed.
- Keep the original PNG if you may need to re-crop; the PDF embeds a raster snapshot.
- Respect the free size and daily conversion limits listed on the tool.
Frequently asked questions
Is PNG to PDF free?
Yes, with a free daily conversion allowance per tool and no watermark. Pro increases limits.
Can I combine multiple PNGs into one PDF?
Yes. Each PNG becomes its own page. Use Move up and Move down to set the page order before converting.
What happens to transparency?
Transparent pixels sit on the white A4 page. The graphic itself stays sharp. If you need a colored background, flatten the PNG first.
Will text in a screenshot be searchable?
No. A screenshot is still an image inside the PDF unless you run OCR separately.
What file size limits apply?
Free conversions follow the MB limit shown on the tool, plus the daily free conversion cap. Pro raises both.
Can I open the PDF on my phone?
Yes. The output is a standard PDF readable in mobile browsers and PDF apps.
Is it safe to convert PNG files here?
Yes for privacy of your document: conversion runs in your browser. Your PNG file is not uploaded to our servers for conversion, and we do not store or read it. Refreshing or closing the page clears it. The website may still use cookies for ads and analytics, which is separate from your file.
Do you store or read my files?
No. For browser-based tools we never receive your file contents. Quota checks only count how many conversions you run.
