Free Tools for Businesses: A Practical Guide by Department

Most of the document work a small business does isn't complicated enough to justify a paid subscription — it's converting a file, compressing something before it's emailed, or pulling data out of a PDF. Here's how the free tools on this site map to the recurring tasks that show up across marketing, finance, HR, legal, and operations.

Marketing

• Resizing images for different platforms. Resize Image and Compress Image get assets down to the right dimensions and file size before they go into an ad platform or CMS with its own limits.
• Turning a deck into something shareable. PowerPoint to PDF converts a presentation into a format anyone can open, without needing PowerPoint installed.

Finance and accounting

• Turning bank or expense exports into a workbook. CSV to Excel converts raw exports into a real spreadsheet, ready to format and share.
• Digitizing paper receipts. Scan to PDF plus OCR turns a stack of paper into searchable, filed records instead of a shoebox.
• Combining invoices into one file for a batch submission. Merge PDF assembles them in order, in seconds.

HR

• Application and onboarding paperwork. Fill PDF Forms lets candidates and new hires type directly into a form instead of printing, filling by hand, and scanning it back.
• Collecting a signature on an offer letter or policy acknowledgment. Request a Signaturesends a document out and tracks who's signed it.

Legal

• Checking what changed between two versions of a contract. Compare PDFs highlights the differences instead of relying on someone catching them by eye.
• Permanently removing sensitive content before sharing. Redact PDF — critically, this removes the content itself, not just a visual overlay, which matters for anything with real confidentiality requirements.
• Filing that requires the PDF/A archival standard. PDF to PDF/A handles the conversion so the file meets long-term retention requirements.

Operations

• Keeping outgoing files under email or portal size limits. Compress PDF handles this in one step.
• Recovering a corrupted file that opens broken in one viewer but not another — Repair PDF rebuilds it before you assume the content is lost.
• Bulk-converting exported data between JSON and XML when moving it between internal systems, with JSON to XML.

Why this is worth setting up as a habit, not a one-off

None of these tasks are individually expensive to do manually — the cost is that they're constant. A business doing any real volume of paperwork runs into some version of "compress this," "combine these," or "make this searchable" multiple times a week. Having a fast, free, no-signup path for each one — bookmarked, not re-discovered every time — is what actually adds up over a year, far more than any single conversion does on its own.
