How to generate 50+ meta tags at once
Batch processing is the real time-saver. This Open Graph Preview guide shows how to handle a whole folder of meta tags in one pass.
Doing one meta tag at a time is fine. Doing 50 of them is a different problem entirely — and exactly where most browser tools fall apart. Open Graph Preview handles batches by design, processing them through the same in-browser pipeline as single files without re-uploading anything.
Launch the tool: Open Graph Preview — Browser-only. Nothing is sent to a server.
The batch workflow
- Open Open Graph Preview.
- Select all the meta tags at once. Drag a whole folder onto the drop area, or use Ctrl/Cmd+A in the file picker.
- Set the options once — they apply to every meta tag in the batch.
- Start the run. Open Graph Preview processes them sequentially; progress shows file-by-file completion.
- Download — usually a single ZIP with every result inside, named after the original meta tags.
How long does a batch take?
Roughly the same time as one meta tag, multiplied by the count. A small meta tag processes in well under a second; 50 of them take under a minute. Larger meta tags (video, scanned PDFs) scale linearly — budget a few seconds per file. Your CPU is the limit, not the network, because nothing is being uploaded.
Memory and browser limits
Open Graph Preview stages the work so the browser only holds a few meta tags in memory at once, not all 50. This means you can safely batch hundreds of files on a normal laptop — the limit is your patience, not the browser's RAM.

When batching saves real time
Examples where batch processing pays off:
- Wedding photo cleanup — a thousand-image album, processed at once, downloaded as a single ZIP.
- Monthly invoice archive — every PDF for a year, compressed and stripped of metadata in one pass.
- Bulk format conversion — every HEIC photo from a trip, converted to JPG for sharing.
- Document scan run — a folder of scanner output, all run through the same cleanup, all named consistently.
Frequently asked questions
Does the ZIP download work on mobile?
Yes — both iOS and Android handle ZIPs from browser downloads. You can extract them with the built-in file manager.
What if one file in the batch fails?
Open Graph Preview skips the failed file, continues with the rest, and reports the error at the end. You can re-run just the failed one separately.
Is there a maximum batch size?
Not a hard one — we've seen users process 500+ files in a single session. The practical limit is your computer's patience.
Can I cancel a batch midway?
Yes — close the tab. Open Graph Preview doesn't keep anything; files already processed are saved in your downloads, unfinished ones are simply lost.
