How to Find the Original File from a Screenshot or Export on Mac
Arun Gopidas
A client emails a PDF and asks for changes. You exported it months ago, sent it, and have absolutely no memory of where the source file is. The PDF is right in front of you. The Illustrator file — or the Photoshop master, or the InDesign document — is somewhere on your Mac or one of your drives.
This is one of the most specific and infuriating file-hunt scenarios in design work. You have one version of the file. You need the other. And the only information you have is the export itself.
Here's how to use that export to find the original.
Why This Is Hard Without the Right Tool
The obvious approach is to search Spotlight for something you remember about the filename. But if you named the working file something like "Acme-BrandBook-v4-FINAL-sent.ai" and it's been eight months, that name isn't coming back to you.
The second obvious approach is to dig through folders. This works eventually but it's not fast, and it doesn't scale across multiple drives.
What you need is a search that starts from the export and works backward — extracting what's meaningful from the file you have, then using that to locate the source.
Two Methods, Depending on What You're Holding
Method 1: Reverse File Search (for PDFs and exports with text)
If the export is a text-based PDF — anything from an Illustrator, InDesign, or Sketch export that preserves text layers — you can drop it directly into reverscan and it will extract the full text content and search your indexed library for related files.
Here's why this works: the text inside your export (headlines, body copy, labels, captions) also exists in the source file. reverscan extracts that text from the PDF you're holding, builds a query from the meaningful terms, and searches your indexed files for content matches. The source file — whether it's an AI, INDD, Sketch, or PDF master — surfaces because it contains the same content.
Step 1 — Make sure your files are indexed
Open reverscan and check the Drives tab. If you haven't indexed the drive where the source file likely lives, add it now. Indexing runs in the background.
Step 2 — Run Deep Scan (if you haven't already)
For the reverse search to find source files in formats like PSD, Affinity, XD, or InDesign, those files need to have been OCR'd by reverscan's Deep Scan. Deep Scan renders these files to images and extracts their visible text, making them content-searchable. It's a one-time operation per drive.
Step 3 — Drop the export into reverscan
Open the Search tab. Drag the PDF or export file into the drop zone. reverscan extracts the content and immediately searches your index.
Step 4 — Review the results
Results are ranked by relevance: exact filename matches first, then filename token matches, then content matches. The working file will typically appear in the first few results if it's been indexed.

Method 2: Visual Similarity Search (for images and visual exports)
If what you're holding is a JPG, PNG, or screenshot — not a text PDF — visual similarity search is the better approach.
You drop the image. reverscan generates a visual embedding for it using Apple Vision and compares it against the embeddings of every indexed image in your library. Files that look visually similar (similarity score ≥ 0.50) appear as results.
This finds:
The original high-resolution version of a compressed export
Other crops or colour treatments of the same image
Similar frames from the same shoot or project
Screenshots you took of a design reference

This method won't directly surface the PSD source behind a JPG — it finds similar images, not source files. But it will help you locate the right folder, the right project, or the right version to narrow your search.
Which Method to Use
What you're holding | Best method |
|---|---|
A text-based PDF export | Reverse file search — drop the PDF |
A JPG or PNG image | Visual similarity search — drop the image |
An image-based PDF (no text layer) | Reverse file search — reverscan auto-falls back to OCR |
A screenshot of a design | Visual similarity search |
A PNG export with lots of visible text | Try both — reverse search uses OCR on the image |
A Practical Example
Say a client sends back a PDF of the brand guidelines you delivered. They want the headline font changed. You have the PDF. You need the InDesign source.
Make sure your Mac and project drives are indexed in reverscan
Drag the PDF into reverscan's search drop zone
reverscan extracts the full text — project title, client name, section headers, body copy
It searches your indexed InDesign, Sketch, AI, and PDF files for content matches
The INDD source surfaces in results — click to reveal it in Finder
If the file is on a drive you haven't plugged in recently, it'll still show up with an "Unplugged" badge. You'll know exactly which drive to grab.
Tips
Always index your project drives. The more drives reverscan has scanned, the more it can find. External drives stay searchable even when disconnected — reverscan keeps the index regardless.
Run Deep Scan on each drive once. Deep Scan unlocks content search for PSD, InDesign, Affinity, and XD files. Without it, those files are only findable by filename. After Deep Scan, they're findable by everything written inside them.
Drop the highest-quality version you have. A crisp, text-rich PDF produces better keyword extraction than a low-res screenshot. If the client sent you a compressed image and you have the original PDF export somewhere, use the PDF.
Frequently Asked Questions
Can I find the PSD behind a JPG?
Not directly via content — a JPG has no text to match against the PSD. But visual similarity search will find indexed images that look like the JPG. If the PSD lives in the same project folder as similar images, those images will surface and lead you to the folder.
What if the source file was renamed or moved?
reverscan searches by content, not by filename or location. As long as the source file is indexed and contains content that matches what's in the export, it will surface regardless of what it's called or where it lives now.
My source file is on a drive I haven't indexed yet — what do I do?
Add the drive in reverscan's Drives tab, let it index, then run the search again. External drives can be added and indexed at any time.
What if the PDF export has no text layer (e.g., it was printed and scanned)?
reverscan automatically falls back to OCR when a PDF has no text layer. OCR quality depends on the scan resolution — a clear scan will produce good text extraction; a blurry or skewed scan may not.
Does this work for Figma exports?
Yes. Export from Figma as a PDF and drop it into reverscan. It extracts the full text from the PDF and searches your indexed files for matches. The Figma file itself (.fig) isn't text-searchable without Deep Scan, but the export will find other files — like an AI or PDF master — that share the same content.
Can I find a source file that's on an unplugged drive?
Yes. reverscan keeps its index even when drives are disconnected. If the source file was indexed while the drive was connected, it will appear in results with an "Unplugged" badge.
The working file exists. You made it, you saved it, it's somewhere on a drive you own. Download reverscan free and let the export you're already holding find it for you.
