Screenshot to PDF
Combine PNG / JPG / WebP screenshots into a single shareable PDF — every page hugs the screenshot exactly, with optional cover title/subtitle/date, per-page captions and page numbers. Free, private, browser-only.
What is the Screenshot to PDF?
A screenshot-to-PDF tool stitches multiple screenshots into one shareable PDF — the easiest way to ship a bug report, design walkthrough or step-by-step guide. Toollyz Screenshot to PDF runs everything in your browser using the open-source pdf-lib library. Drop up to 30 PNG, JPG or WebP screenshots; each becomes a page sized exactly to the image (pixels are treated as PDF points so there's zero scaling). Add a 2-line caption under each screenshot — it word-wraps to the page width — and a footer page number ("Page n / N") that includes the optional cover page in the count. The cover page can have a title (Helvetica Bold 32pt), subtitle (16pt) and today's date (11pt). Configure the page background colour, text colour and outer margin. WebP screenshots are transparently re-encoded to PNG since the PDF spec doesn't carry WebP. The final PDF downloads with whatever filename you set; nothing is uploaded.

Frequently asked questions
How does this differ from the regular Image to PDF tool?
Image to PDF lets you pick A4 / A3 / Letter / Legal / Custom / Auto page sizes and Fit / Fill / Stretch layout — useful for printable photo books. Screenshot to PDF is opinionated: every page hugs the screenshot exactly (no scaling), and it adds a cover page, per-page captions and page numbers that are perfect for bug reports and walkthroughs.
How are the page sizes calculated?
Image pixels are treated as PDF points (1 pt = 1/72 in). A 1280×800 screenshot becomes a 1280×800 pt page (plus margin, caption and footer space). The resulting PDF reads at native size in most viewers.
How long can a caption be?
Captions word-wrap to two lines under each screenshot. If your caption needs more, drop a separate text screenshot or shorten it; this tool is intentionally minimal to keep reports skimmable.
Does the cover page count toward the page numbers?
Yes — if you set a cover title (or subtitle or date), the cover is page 1, the first screenshot is page 2, and so on. The footer reads "Page n / N" with N including the cover.
Why are my WebP screenshots re-encoded?
The PDF specification supports JPEG and PNG image streams (DCT and Flate filters) but not WebP. Toollyz transparently decodes WebP via a 2D canvas and embeds the result as PNG. Visually identical; the encoded size is slightly larger than the original WebP.
What if my screenshot is very wide?
The page becomes that wide — most PDF viewers handle ultra-wide pages by fitting to width. If the resulting page is wider than 2048 pt, consider resizing the source screenshot first (Toollyz Image Resizer can do this).
Can I export a Word document instead?
Not from this tool — the PDF output is the goal. You can drag the PDF into Word's "Insert as Object" or rasterise pages first via the PDF to Image Converter.
Are my files saved anywhere?
No. Toollyz has no backend — screenshots are loaded into memory while the page is open and discarded on reload. Settings save to localStorage.
Does it work on mobile?
Yes. The picker uses your phone's camera roll, the queue scrolls and building works in any modern mobile browser. Very large screenshot batches may strain mobile memory; if a build fails, retry with fewer.
Is this Screenshot to PDF tool free?
Completely free with no signup and no limits. Build as many reports as you like — privately in your browser.
