LocalFlow: the PDF and document workflow studio in your browser

Automate batch document processing: compress, merge, anonymize, extract, with no heavy software and no upload.

Built for admin, legal, HR and compliance teams: sensitive PDFs stay on your machine.

Open LocalFlowSee PDF tools

LocalFlow document processes your PDFs 100% locally, with no upload during the chain. You chain compress, merge, redact / blur faces, clean properties and extract on your machine; output can hand off to a FileVert transfer. The image workflow has its own feature page.

The document journey in 5 bubbles

From PDF batch import to output: a visual local chain, no re-drop between steps.

01Local import

Drop your PDFs

Drag a folder or a set of documents. The tree is preserved as soon as you enter the studio.

  • Batches and subfolders accepted
  • No upload to a server
  • Ready for the sequence
A
B
C
02Visual chain

Stack PDF bubbles

Build: compress, merge, split, anonymize, watermark, extract text… for the real need.

  • Document bricks
  • Rename: prefix, counter, date
  • Watermark and PDF markings
03Execution

Run the sequence

One global run processes the whole batch locally. Progress stays readable, including on mobile.

  • In-browser processing
  • Device budget controlled
  • No cloud queue
04Automation

Save the sequence

Freeze the chain to replay in one click, e.g. compress → anonymize → rename (FileVert offer).

  • Example: compress → anonymize → numbered names
  • Settings remembered
  • Custom studio
FileVert
05Outputs

Exit your way

Local folder, structured ZIP, or handoff to a FileVert transfer. You keep control of the output.

  • Folders preserved
  • Optional ZIP archive
  • FileVert transfer gateway

What online PDF suites force today

Compress, merge, split, anonymize: each gesture opens another cloud tab. You drop contracts, payslips, medical files or ID scans. The batch leaves, a third-party server sees everything, then you start over for the next step. For a serious document flow, that is too much friction and too much exposure.

Without LocalFlow document

  • •One cloud tool, one action, one re-download
  • •Confidential documents exposed to third-party servers
  • •PDF batches rebuilt at every step
  • •Compliance hard to justify to a DPO

With LocalFlow document

  • One sequence: compress → anonymize → extract → rename
  • Local execution: no upload during processing
  • Batches and folders that follow from brick to brick
  • A workspace built to chain steps without distraction

A visual, modular document chain

LocalFlow turns your PDF workflow into horizontal action bubbles: compress, merge, split, anonymize, watermark, extract text or images, prepare prepress. An agile alternative to captive cloud suites and heavy Acrobat scripts.

Clear path

See the full batch journey at a glance: from import to output, without scattered tabs.

Document agility

Add, reorder or configure each brick (compression, anonymization, extraction) before global execution.

Compliance focus

A clean, ad-free UI designed to process sensitive dossiers without distraction.

PDF batch persistence and folder tree respect

When you switch to sequence mode from a PDF tool, batches, folders and settings follow. Moving to the next brick needs no re-drop. Renaming targets files; folders stay intact.

Confidentiality and GDPR intent, by design

Document audiences are not photo audiences: PII, trade secrets, ID documents. LocalFlow processes locally so the cloud never sees content during production.

No transit during processing

Compression, anonymization and extraction run in the browser. No opaque server queue.

Anonymize before extract

Chain redaction then text extraction: the .txt can leave already masked (*******) if anonymization ran.

Justifiable to a DPO

Client-side architecture: a clear argument to limit off-device transfers of personal documents.

Ultra-fast ephemeral storage (OPFS)

LocalFlow uses a private workspace in browser memory. Your PDFs move bubble to bubble with no external exchange during the chain.

Local execution

No network upload, no cloud queue: compute runs on your machine.

Contained data

Contracts, HR, legal and client files stay on the device during active production.

Sobriety by architecture

No remote infrastructure for transient processing: sobriety comes from the design.

Also in the field

Bounded processing respects the device budget. Progress stays readable on phones for large PDFs, with no forced app install.

One chain, adapted outputs

Once the sequence is validated, you keep control of the output, with no cloud lock-in.

  • Immediate local save: folders kept, files optionally renamed
  • Structured ZIP archive
  • Handoff to a FileVert transfer to share the result responsibly

Frequently asked questions

Automate a local PDF workflow, without a cloud suite

How is LocalFlow document different from online PDF suites (Smallpdf, ILovePDF, etc.)?

Cloud suites process one action at a time after upload. LocalFlow is a workflow studio: you chain compress, merge, anonymize, extract locally. Documents do not transit through a third-party server during processing.

Why does a 100% local PDF workflow matter for legal, HR and compliance teams?

These teams handle PII, contracts and ID documents. In-browser processing (OPFS) limits cloud exposure and gives DPOs a clear argument: content does not leave the device during production.

Can I anonymize a PDF then extract already masked text?

Yes. If the anonymize brick runs before extract, the text file can leave with sensitive content replaced by asterisks (*******). Without anonymization, extraction stays raw.

Which PDF bricks can I chain in LocalFlow?

Compress and prepare, merge, split, anonymize, watermark, extract text or images, batch rename, and other document steps depending on the studio version. Tool pages remain the authority on each isolated gesture.

Does LocalFlow document replace Acrobat Actions or batch scripts?

For many recurring chains (compress → anonymize → rename), yes: you compose visually and can save the sequence (FileVert offer). Local processing stays available without a heavy install.

How is PDF batch persistence kept without cloud storage?

Via the browser OPFS: a temporary sandbox on the device. Folders move from bubble to bubble with no external server during the chain.

What is the difference with the LocalFlow image page?

Same technical studio, different SEO intent and audiences. The image page targets photo production. The document page targets PDF, compliance and admin / legal flows.

How do I share the result after the chain?

Local save, ZIP, or handoff to a FileVert transfer. Send limits follow your FileVert plan.

Do I need to install software?

No. The whole chain runs in the browser, with no mandatory signup for local processing.

Do large PDFs work on mobile too?

Yes, with bounded processing that respects the device budget. Progress stays readable; for heavy batches, a desktop remains more comfortable.
