Images to PDF — Chrome extension

Collects the images (<img>) on the current page, lets you pick the ones you want in a grid, and saves them into a single PDF — one image per A4 page. Localized in English (default) and Russian.

Install

From the prebuilt release (easiest):

1. Download images-to-pdf.zip from the Releases page and unzip it into a permanent folder (don't delete it — the extension runs from there).
2. Open chrome://extensions (or edge://extensions) → enable Developer mode (top-right toggle).
3. Click Load unpacked and select the unzipped folder.
4. The icon appears in the toolbar.

Updating: when a new version ships, download the fresh ZIP and repeat (self-distributed builds don't auto-update).

From source (for development): clone the repository and select the project folder in step 3.

Usage

1. Open any website (http/https).
2. Click the extension icon — a grid of the page's images appears.
3. Small images (< 64×64 px) are hidden by default; toggle "show all" to see them.
4. Tick the images you want (or "Select all").
5. Click Export PDF. On the first export Chrome asks for access to the domains of the selected images — allow it so they can be downloaded. A file named images-<site>-<date>.pdf is downloaded.

Support the developer 💛

If this extension is useful to you, you can support its development with a small crypto tip — thank you!

View / verify on Etherscan

Send only on the Ethereum (ERC-20) network. The same address is also shown with a Copy button inside the extension popup.

How it works

• src/popup.* — UI and orchestration; builds the PDF with jsPDF.
• src/content.js — injected into the page on demand, collects <img> elements.
• src/background.js — service worker, downloads image bytes (bypassing CORS).
• src/lib/*.js — pure logic (filtering, fit-to-page, filename, base64, origins, donate).
• _locales/{en,ru}/messages.json — localized strings.

Permissions: the extension only requests activeTab + scripting. Access to image domains (optional_host_permissions) is requested on demand at export time — scoped to the specific sites.

Development

Unit tests for the pure logic (Node 18+ required):

node --test tests/*.test.js

Regenerate the icons:

python3 tools/make-icons.py

Build the distributable ZIP (output: dist/images-to-pdf.zip):

bash tools/package.sh

Donations: set your USDT (Ethereum / ERC-20) address in DONATE_ADDRESS (src/popup.js) — a "Support the developer" bar with the address and a "Copy" button appears at the bottom of the popup. With the placeholder value it stays hidden.

Store listing copy lives in STORE-LISTING.md; the privacy policy in PRIVACY.md.

Manual checklist (browser testing)

1. On install there's no "read your data on all sites" warning.
2. A page with many images — thumbnails render as proper tiles.
3. Export → permission prompt for the image domain → Allow → PDF.
4. Re-export to the same domain — no second prompt.
5. Decline the prompt → friendly message, button stays active.
6. Page with no images → "No images found"; chrome://extensions → "page isn't supported".
