If you need to convert a PDF to JPG, head over to the PDF to JPG tool. You can extract individual images from the PDF’s pages, or turn whole PDF pages into JPG images. 

Keep Formatting with OCR for Scanned PDFs

Got a scanned PDF that looks like an image? Our OCR technology recognizes text in scanned documents and converts them into fully editable formats. This means you can turn old paper documents into searchable, editable Word files or Excel spreadsheets.

The PDF format has been loved and embraced by individuals and businesses since its initial release back in the 1990s. Here’s why PDFs are still the go-to choice:

• Universal compatibility: Once a file is saved as a PDF, it can be viewed on almost any device across all operating systems, all while retaining its format in a compact size. Other formats, on the other hand, may appear completely different when opened on another PC.

• Professional quality: PDFs look the same on every device—no formatting surprises when sharing important documents like contracts, reports, or portfolios.

• Security features: Files saved as PDFs are extremely secure and can’t be altered without leaving an electronic footprint. Electronic signatures on PDFs can also be validated easily, and PDFs can be protected and secured with a password.

To set a super-secure, encrypted password, head over to our Protect PDF tool.

Your security is our top priority. Here’s how we keep your files safe:

• TLS encryption: All file transfers use secure HTTPS connections.

• Automatic deletion: Your files are automatically deleted after one hour of processing.

• GDPR compliant: We follow strict European data protection standards.

• Secure servers: Your documents are processed on encrypted, secure servers.

• No human access: Only automated systems handle your files during conversion.

If you work on your mobile frequently, check out the free Smallpdf Mobile App. It lets you view, modify, Sign PDF, and of course, convert files to PDF format—right there on your smartphone. 

If you’re a Pro user, we’ll also sync documents saved as PDFs to our online storage system for a centralized document management space. Even when you switch from your mobile phone to a PC or a tablet, the files will always be available whenever you need them.

Sharing a converted file on Smallpdf is simple. Once you’ve converted a file, you’ll find the share function on the result page with two options: 

• Generate a link for others to download your file

• Send it directly to a recipient’s email

You can also save the document on a cloud storage service like Dropbox, OneDrive or Google Drive. It’s right there on the “Download PDF” menu on the result page.

Smallpdf has even created a Dropbox extension, which lets you send files from Dropbox directly to a tool on our site. Of course, when you’re done, you can save the file back to Dropbox without downloading it to your device first.

Beyond conversion, our AI-powered tools can summarize long PDFs, translate documents into different languages, and even help you chat with your PDFs to extract key information quickly. Perfect for busy professionals who need to process documents efficiently.

Most files convert without problems, but a few issues can slow things down. These quick checks usually help.

The Upload Will Not Start

• Make sure your internet connection is stable.

• Refresh the page and try again.

• If you are using multiple browser tabs, close the upload in other tabs first.

The File Is Very Large

• Large documents may take longer to process.

• Try closing other apps or browser windows to free up memory.

• Convert directly from a cloud service like Google Drive or Dropbox to avoid slow local uploads.

The File Looks Corrupted or Will Not Open

• Open the original file on your device to confirm it works.

• If it fails to open locally, try exporting or saving a fresh copy before converting.

• For scanned documents, ensure the file is not cut off or missing pages.

The Tool Says the Format Is Not Supported

• Check the file extension and make sure it is one of the common formats (Word, Excel, PPT, JPG, PNG, etc.).

• Re-save the file in its native app. This often fixes hidden formatting problems.

• If it is a rare or specialized format, export it to PDF or a standard format first.

Images Look Blurry After Conversion

• Check the resolution of the original image, very small images may not scale well.

• Re-scan documents at a higher DPI before converting.

• Avoid screenshots when scanning text-heavy documents.

The Conversion Is Slow

• Clear your browser cache and restart the browser.

• Try switching to a different browser for a fresh session.

• Large or graphic-heavy files may take longer to process, so allow a bit more time.

If you’re still stuck, you can always try converting the file again or upload it directly from cloud storage to avoid local issues.
