Will my screenshot stay sharp?

Mostly, with a caveat worth knowing. Pages are stored as JPEG, and JPEG softens hard edges slightly — which is exactly what text is made of. At the Best quality setting the effect is very hard to see; at Small it is noticeable on small text. If perfect text edges matter, a PDF made this way is not the right vehicle, and printing the original to PDF from the application it came from is.

What happens to transparency?

It becomes white. PDF pages here are opaque, and a transparent PNG has to be composited onto something — white is what a page is. If a transparent background is the point of the image, a PDF is probably not what you want.

Can I combine several screenshots into one PDF?

Yes, up to thirty, each becoming a page in the order you set. This is the usual case: a set of screenshots documenting a bug, a process, or a conversation, that needs to arrive as one file rather than as a dozen attachments in an unpredictable order.

Would a single tall image be better than a multi-page PDF?

Sometimes, and it is worth considering. A conversation or a long web page reads better as one continuous image than as pages that cut it into arbitrary sections. The merge tool will stack your screenshots vertically into a single picture; use a PDF when the recipient expects a document and an image when they expect to scroll.

How do I convert a PNG to PDF?

Add your PNG files below, order them with the arrow buttons, choose a page size and press create. Pages are embedded as JPEG, so a PNG screenshot becomes a JPEG of a screenshot — use the Best quality setting when the image contains small text, because that is where the difference shows.

The honest caveat, first

Pages in the PDF this page produces are stored as JPEG. That is a real limitation and it matters more for PNGs than for photographs, because PNGs are usually screenshots, and screenshots are full of the hard edges JPEG handles worst.

In practice, at the Best quality setting, you will struggle to see it — the softening is slight and mostly invisible at ordinary reading sizes. At Small it becomes visible around small text as a faint shimmer. So: Best for anything with text in it, and lower settings only when a file size limit forces the issue.

If crisp text is genuinely essential, the better route is not this page at all. Printing to PDF from the application the content came from keeps text as text — searchable, selectable, and perfectly sharp at any zoom.

What this is good for

Assembling a set of screenshots into one document that arrives in order. Documenting a bug or a process step by step. Turning a scanned form back into something a portal will accept. Sending a sequence of images to someone who asked for “a PDF” and meant “one file”.

The ordering controls are the part that earns its keep. Files arrive from a file picker in whatever sequence it chose, and a document whose steps are shuffled is worse than no document.

Transparency becomes white

A PNG can have transparent areas; a PDF page cannot be transparent in this tool. Those areas are composited onto white, which is what a page is, and for a screenshot with rounded corners or a drop shadow that is exactly right.

If the transparency is the point — a logo intended to sit on a coloured background — a PDF is not the format you want, and keeping it as an image is.

Or make one long image instead

A chat conversation, a long web page or a settings screen captured in pieces often reads better as a single tall picture than as pages with arbitrary breaks through the middle of it. The merge tool stacks screenshots vertically into one image, matching their widths so the seams line up.

Use a PDF when the person receiving it expects a document. Use one long image when they expect to scroll.

Nothing is uploaded

Screenshots are frequently of private things — conversations, account pages, medical portals, internal systems. Every file here is opened, re-encoded and written into the PDF by your own browser. There is no server on this site that could receive one, which you can confirm in the network tab or by disconnecting after the page has loaded.
