The agency that made the brochure is gone. Or the designer left and took the working files. Or the client sends a PDF and says "just tweak the date." You have the PDF — a flattened, finished artefact — and you need the editable InDesign source back.
There are a few honest ways to do that. None is magic, and the right one depends on how much you'll pay, whether you own InDesign, and how forgiving the file is. Here's the full landscape, fairly.
1. Rebuild it by hand in InDesign. Place the PDF on the pasteboard as a reference, then retype the text, re-set the type, and recreate the graphics on top. Free (if you have InDesign), and 100% accurate because you made it. Also slow — an afternoon for a single complex page — and it doesn't scale past a page or two.
2. Desktop plugins — Markzware PDF2DTP / Recosoft PDF2ID. Mature, powerful InDesign plugins that convert a PDF into an editable document inside InDesign. Roughly $199–$299 (or subscription), Windows/Mac desktop, and they require a licensed InDesign to run. If you convert PDFs constantly and live in InDesign, they're the professional standard.
3. "AI" PDF converters. Some newer tools use AI/LLMs to "reconstruct" a document. The risk is exactly that word — reconstruct. AI can invent text it couldn't read cleanly, or reflow a layout into something plausible-but-wrong. For a legal, financial or brand document, "plausible" is a liability.
4. SourceBack (this one). A web tool: upload the PDF, get an editable InDesign file (IDML) back. Per-file, with a free fidelity preview before you pay, no InDesign or install needed to convert. It's deterministic — it rebuilds the source from the file's own text and vectors, invents nothing — and it's honest about limits: flat or scanned pages with no recoverable layer are clearly declined, not faked.
| Route | Cost | InDesign required | Preview before you commit | Handles scans | Best for |
|---|---|---|---|---|---|
| Rebuild by hand | Free (if you own InDesign) | Yes | — | You redraw it | 1–2 pages, total control |
| PDF2ID / PDF2DTP | ~$199–299 | Yes | — | Partial | High volume, desktop pros |
| AI converters | Varies | No | Rarely | Risky | Rough drafts, low-stakes |
| SourceBack | Per file, free preview | No | Yes — per-page fidelity | Declined, not faked | Occasional recovery, honesty |
No AI, no guessing. The engine:
so it's flagged, not mangled. 2. Extracts the real content — the text (with its fonts, sizes and positions), the vector shapes, and the placed images, straight from the PDF's own data. 3. Rebuilds it as IDML — a native InDesign package: live text, editable vectors, placed images. 4. Checks its own work — it renders the rebuilt page and diffs it against the original, producing a per-page fidelity score and a side-by-side preview. You see exactly what came back before you pay. 5. Declines what it can't recover — if a page is flat/scanned, or only a fraction of its ink is recoverable, it says so honestly rather than shipping a near-empty page.
That verify-and-declare step is the whole point: you're never buying a surprise.

Is this the same as PDF2ID? Same job, different shape: PDF2ID is a ~$299 desktop plugin that runs inside InDesign; SourceBack is a per-file web tool with a free fidelity preview and no install. If you convert constantly, a desktop plugin may pay for itself; if you need the occasional recovery and want to see the fidelity first, the web tool fits better.
Will my fonts come back? The text is editable and fonts are referenced by name. Install the original fonts for an exact match; otherwise InDesign substitutes and the report tells you where.
Can it edit a scanned PDF? No tool can make a scan editable without OCR, and even then you get text, not the original layout. SourceBack declines flat/scanned pages honestly instead of faking them.
Is my file private? Your upload and the result auto-delete within 12 hours, and nothing is reused.
