Are my PDFs uploaded to ArtCraft servers?

Merge and light optimize run in the browser with pdf-lib. We do not send those PDF bytes to Fal or other AI providers. (Your browser still loads the ArtCraft page itself over HTTPS.)

Can I reorder files before merging?

Add PDFs in the order you want them combined. The merge follows the list order shown in the PdfCraft panel (up to the UI file limit).

Does PdfCraft split PDFs or extract pages?

Not in the current deployed build. Today we support merge and a light client-side optimize. Split/extract will get a guide only when that feature ships.

How to Merge PDF Files Online Without Uploading Them

Combine multiple PDFs in your browser with PdfCraft. Merge runs client-side with pdf-lib — PDF bytes are not sent to our AI servers.

Answer in one minute

To merge PDFs in the browser with ArtCraft PdfCraft:

Open PdfCraft Online (or the PdfCraft panel on the homepage).
Switch to Merge and add two or more PDF files.
Keep the list order as the page order you want.
Run Merge and download merged.pdf.

Merge is implemented with pdf-lib in the client (src/lib/pdf-client.ts). Those PDF bytes are not sent to Fal or our AI job pipeline.

Why “without uploading” matters

Many “free PDF merger” sites upload your files to a server. For contracts, IDs, or medical PDFs, that is a hard no. ArtCraft’s PdfCraft merge path is intentionally browser-side: select files → merge in WASM/JS memory → download the result.

(You still load the ArtCraft webpage over HTTPS like any site. The claim here is about PDF payload handling for merge/optimize, not about never contacting a CDN.)

Step-by-step

1. Open PdfCraft

Go to PdfCraft Online and use the live CTA into the PdfCraft workspace, or jump to the homepage PdfCraft section.

2. Choose Merge and add files

Select the Merge tab (not Optimize).
Drop or pick PDFs (the UI caps how many you can attach — stay within the limit).
Confirm each filename appears in the list in the order you want combined.

Need a different order? Clear and re-add files in the correct sequence (current UI follows list order).

3. Merge and download

Click the merge action and wait for the browser to finish. Your download should be a single PDF (default name merged.pdf). Open it once and flip through page boundaries between the source files.

4. Optional: light optimize

The Optimize tab rewrites a single PDF with object streams. It is a light client-side rewrite — not aggressive image recompression or “magic 90% smaller” marketing.

Privacy summary

Merge / optimize: processed in your browser with pdf-lib; not uploaded to our AI providers.
PhotoCraft AI tools (background removal, etc.) do upload images to cloud inference — different product path.
