Privacy by design
Temporary files expire automatically. Document content is never used for ad targeting.
No account walls. No complex settings. Just upload, configure, and download.
Organised by task type. Search or browse by category — every tool works instantly as a guest.
Built around your privacy and time — not around ads that interrupt your work.
Temporary files expire automatically. Document content is never used for ad targeting.
Task outputs are modeled so future workflows can reuse results without re-uploading.
Sponsored messages appear on tool entry and download — never inside the tool workspace.
Upload, preview, options, and processing in one predictable flow.
File type, count, size, and sensitive task options are checked before processing starts.
Every tool has structured data, canonical metadata, and crawlable links.
From students submitting assignments to teams managing document workflows.
Merge lecture slides, compress scanned assignments, and add page numbers before submission.
Protect confidential contracts, extract key pages, and convert PDFs to images for presentations.
Batch-process invoices, watermark drafts with version labels, and organize document sets.
“Merged 12 contracts in under a minute. Much cleaner than anything else I've tried.”
“Love that I don't need to sign up just to compress a single PDF.”
“The watermark tool saved me so much time on draft approvals.”
Start free. Upgrade when you need more.
No account is required for any tool. Guest usage allows files up to 25 MB and up to 5 files per task. Creating an account (free) raises those limits and saves your task history.
Uploaded files are stored temporarily and expire automatically after two hours. File content is never used for ad targeting or shared with third parties.
Before a file is processed, you confirm that you have the rights to upload and modify it, and you allow OpenPDFKit to temporarily process it only for the free PDF tool you selected.
Ads appear as short interstitial moments when you open a tool from the catalog and before downloading a completed result — never inside the tool workspace while you are working.
Most tools accept PDF. The Image to PDF tool accepts JPG, PNG, and WebP. PDF to JPG converts PDF pages to images.
An API is planned for the Pro tier. If you have a use case, join the Pro waitlist and we will be in touch.
