Frequently asked questions

What is PixelPDF?

PixelPDF provides online tools for converting, organizing, and managing PDF documents. Each tool page describes its supported files, steps, and limitations. Browse the PDF tool directory to choose a task.

How do I convert an image to PDF?

Open Image to PDF, select supported images, arrange them in the order you'd like, and start the conversion. Check the resulting pages and image quality after downloading. The image tool accepts up to 20 images, subject to its file and image limits.

How can I merge multiple PDF files?

Use Merge PDF to select two or more PDFs, arrange their order, and create one output file. Check the combined page limit and inspect the downloaded document.

How do I split a PDF into separate pages?

Open Split PDF and select the pages or page ranges to extract. Page numbers refer to the PDF's page order. Review the new document to make sure it contains the intended pages.

How can I reduce a PDF file size?

Try Compress PDF. It rewrites PDF structure but does not downsample or re-encode embedded images, so image-heavy or already compact files may not become smaller. Check the resulting file size and content.

Which file formats does PixelPDF support?

Formats vary by tool and include PDF, supported image formats, DOCX, XLSX, PPTX, and local HTML input for the HTML converter. Check the supported formats page and the selected tool's instructions before uploading.

Why is my file not processing?

The file may be damaged, password-protected, over a displayed limit, or in a format the selected tool does not accept. Confirm that the file opens locally, choose the matching tool, and review the PDF troubleshooting steps.

What should I do if a download fails?

Check your browser's download list and available device storage, then retry if the transfer did not complete. If processing must be repeated, keep the original file and verify the new download before relying on it.

Can I use PixelPDF on a mobile phone?

The website uses a responsive layout and your browser's file picker. File selection and saving behavior depend on your device and browser, so check that the upload completes and open the downloaded file to verify it.

How do I unlock or protect a PDF?

For a document you are authorized to modify, Unlock PDF requires the correct password. To create a password-protected copy, use Protect PDF and follow its password requirements. Unknown passwords are not guessed or recovered.

Why does a converted document look different from the original?

Some conversions reflow text or reconstruct document structure rather than preserving the original page design. For example, PDF to Word extracts selectable text into editable paragraphs, and table extraction is heuristic. Review important outputs against the source.

How can I report a technical problem?

Read the Contact page for the channel available on this deployment. A public email or message form may not be configured. The troubleshooting page is available in the meantime; do not share passwords or confidential documents in a report.

Privacy and security

Processing tools send selected files and options to the server to perform the requested operation. The application uses temporary job directories and attempts cleanup, but this is not a guarantee about hosting, backups, or infrastructure retention. Upload only files you are authorized to process, and avoid entering confidential information unless you accept the applicable risks.

Contact and further help

The Contact page shows a public email channel only when one is configured for the current deployment; no response time is promised. If no channel is available, use the guides, troubleshooting steps, FAQ, and tool-specific instructions on this site.
