Frequently asked questions

No. There is no backend server and no API to upload to. The site is static files, and all processing happens inside your browser tab using Web Workers. You can confirm it yourself: open your browser's Network tab and use the tool — after the page loads, you will see no further requests.

It is free, and there is no account, no sign-up and no paid tier. The site is supported by advertising.

Not unless you explicitly choose to. By default files are only read. The optional Organize files on disk feature shows every rename and move before it happens, and a move requires typing a confirmation word and writes an undo manifest. Nothing is ever permanently erased — photos you delete are moved into a _deleted folder, because a web page cannot use your operating system's recycle bin.

In IndexedDB, your browser's local storage, on your own computer. It holds project metadata and small thumbnails — never full-resolution photos. Deleting a project in the tool, or clearing site data in your browser, removes it.

JPEG, PNG and WebP are fully supported. HEIC and HEIF from iPhones are decoded as well. RAW files and video clips are tracked so the organiser can file them into folders, but they are never decoded, displayed or printed.

It recognises and files RAW formats including ARW, SR2, CR2, CR3, NEF, RAF, ORF, RW2, PEF, DNG and more — but it cannot develop them, because browsers have no RAW decoder. Shoot RAW+JPEG if you want those shots in an album: the JPEG goes in the album and the RAW is filed alongside it, renamed to match so the pair stays together.

They are tracked as companions and filed by date into their own folder, so an organise run does not leave clips stranded in the folder your photos just left. There is no playback, thumbnailing or editing.

Those files probably carry no EXIF capture time, so the file modification date is used instead — and copying files resets that. Screenshots, downloaded images and files re-saved by some apps commonly have no EXIF timestamp at all.

Almost always because the printer dialog had "fit to page" or "shrink oversized pages" enabled. Set scaling to 100% or "actual size" and print again, then measure a trim mark to confirm.

The effective resolution of each photo after cropping, at the size it will actually print. Above roughly 300 DPI is crisp; 200–300 is fine at arm's length; below 200 will look soft. Zooming into a photo lowers the figure, correctly, since zooming discards pixels.

Plain paper is fine for proofs, but 200–250 gsm matte or satin card gives far better colour and survives handling. Always print one proof on plain paper before committing card stock.

No. The default output is a PDF with trim marks you can cut by hand with a guillotine or craft knife, and the folded booklet layout needs no cutting at all. Cutter support is entirely optional.

Yes, if you use DXF — which is the default for exactly this reason. DXF import and print-and-cut both work in the free basic edition. SVG import requires the paid Designer Edition. Note that DXF carries no dependable size information, so check the imported outline measures what the tool says it should.

Any modern desktop browser can import, organise, lay out and export a PDF. Writing to disk — which the optional folder organiser needs — relies on the File System Access API and works only in Chromium-based browsers such as Chrome and Edge. Those features are simply hidden elsewhere.

The interface is usable but not the intended experience: mobile browsers do not offer folder pickers or file writing, and laying out print pages on a small screen is awkward. Use a desktop or laptop.

It is built for folders of a few thousand. Two thousand photos process in well under a minute on a normal laptop, and the grid renders only the tiles currently on screen, so scrolling stays smooth however large the folder.

Browsers deliberately do not keep file access permissions across reloads. Your project, album and thumbnails are restored from local storage, but the original files have to be re-attached — one click on Reconnect in Chrome or Edge, or re-picking the folder elsewhere.

Once the page has loaded it needs no network for anything, so losing your connection mid-session will not stop you working. There is no installable offline app at present.
