How can we help?

Blackpdf is an all-in-one PDF platform that lets you compress, merge, split, convert, protect, unlock, edit, and do much more with your PDF files — directly in your browser. No software installation required.

You can use basic tools without an account. Creating a free account gives you access to activity history, saved passwords, and limited Pro features. Upgrading unlocks unlimited access.

Blackpdf primarily works with PDF files. For conversions, we support PDF to Word (DOCX), PDF to images (PNG, JPG), Word to PDF, images to PDF, and more.

Free users can process files up to 25MB. Pro users up to 50MB and Business users up to 100MB.

Go to the Compress PDF tool, upload your file, choose a compression level (low, medium, or high), and click compress. Your file will be processed and ready for download in seconds.

Yes. Use the Merge PDF tool to combine multiple PDF files into one. You can drag and drop to reorder pages before merging.

Use the Protect PDF tool. Upload your file, set a password, and download the protected version. You can optionally save the password for future access.

Yes. The Edit PDF tool lets you add text, images, annotations, and shapes to your PDF. For full text editing, you can convert to Word, edit, and convert back.

Workflows let you chain multiple PDF tools together. For example: unlock, flatten, compress, and protect — all in one step. Drop your files once and every step runs automatically. Available to Pro and Business users.

Go to Settings > Account > Change Password. Enter your current password and your new password. If you signed up with Google, you won't have a password to change.

Yes. Click "Sign in with Google" on the login page. If you already have an account with the same email, your Google account will be linked to it automatically.

Go to Settings > Account and scroll to the bottom. Click "Delete my account" and follow the confirmation steps. This action is permanent and cannot be undone.

When you protect or unlock PDFs, you can save the passwords locally on your device for quick reuse. Pro and Business users can enable cloud sync to access saved passwords across devices with AES-256-GCM encryption.

Pro and Business users can sync saved passwords, signatures, and stamps across devices. Data is encrypted before being stored on our servers. You can enable or disable sync from Settings > Account.

Business plan subscribers can create a team with up to 5 members. Team members get access to Business features and can share passwords, signatures, watermarks, workflows, and files. Team members don't need their own paid subscription. Manage teams from Settings > Teams.

Yes. You can request a copy of your personal data (account info, processing history, synced passwords) by contacting support@blackpdf.com. We'll provide it in a machine-readable format within 30 days.

Pro ($7/mo or $67/year) — Unlimited Pro features, 50MB max file size, priority processing, 3 active workflows, cloud-synced passwords and signatures, shared file links (24h), no ads, and email support.

Yes. Pro comes with a 7-day free trial. No credit card required to start.

Go to Settings > Plan and click "Upgrade" on the plan you want. You'll be taken to our secure checkout powered by Paddle. You can also upgrade from the Pricing page.

Yes, you can cancel anytime from Settings > Plan. You'll keep access to paid features until the end of your current billing period. After that, your account reverts to the Free tier.

Downgrades take effect at the end of your billing period. When downgrading:

- Features exclusive to your higher plan become unavailable.
- If you have a team (Business), members lose access to Business features. Team data is retained for 30 days.
- Workflows exceeding your new plan's limit are deactivated (not deleted).
- Cloud-synced passwords and signatures stop syncing but are retained for 30 days.

Yes. You can request a full refund within 7 days of your initial purchase by contacting support@blackpdf.com. Refund requests for auto-renewal charges must be made within 48 hours. After these windows, no refunds are provided — but you can cancel anytime and keep access until the end of your billing period.

All payments are processed by Paddle, which acts as our Merchant of Record. Paddle handles invoicing, sales tax, and VAT compliance. We accept major credit cards, PayPal, and Apple Pay. Blackpdf never has access to your credit card details.

Yes. Annual plans save you 20% compared to monthly billing. Pro is $67/year ($6/mo) and Business is $229/year ($19/mo). You can switch between monthly and annual from Settings > Plan.

Yes. All file transfers use 256-bit TLS encryption. Files processed on our servers are automatically deleted after processing is complete. We never access, read, or share the content of your files.

Processed files are deleted immediately after processing. Workflow output files are retained until their expiry period passes. Shared file links expire after 24 hours, and the associated files are deleted when the link expires or is revoked.

No. We do not sell, rent, or trade your personal data. We use essential third-party services: Paddle for payment processing, Google Analytics for anonymous usage analytics, Google for OAuth sign-in, and Resend for transactional emails. None of these services have access to your file content. See our Privacy Policy for details.

Saved passwords are encrypted using AES-256-GCM before being stored. For cloud-synced passwords (Pro and Business), encryption happens before data leaves your device. We cannot read your saved passwords.
