High Quality
PyMuPDF renders pages at 150 DPI — the ideal balance of sharpness and file size.
What Does the Convert Tool Do?
The Convert tool handles two directions of file conversion:
- Images to PDF — Combines one or more JPG or PNG files into a single, properly formatted PDF document. Each image becomes one page, sized to match the image dimensions exactly.
- PDF to Images — Exports each page of a PDF as a PNG image at 150 DPI, delivered as a ZIP archive containing numbered image files.
Both directions are lossless in the sense that no content is added, removed, or altered — the conversion is a structural reformatting, not a re-interpretation of the content.
When to Use Image to PDF
- Smartphone receipt photos — Converting photos of receipts into a PDF expense report for submission or tax filing.
- Scanned documents — A flatbed scanner typically saves images (TIFF, JPG). Converting to PDF makes them easier to share and archive.
- Artwork and portfolios — Combining multiple artwork photos into a single portfolio PDF for gallery or client submission.
- Homework and assignments — Students photograph handwritten work and convert the photos to PDF for submission to an LMS or email.
- ID and passport copies — Converting phone photos of ID documents to PDF for form submissions and applications.
- Product photos — Creating a product catalogue PDF from individual product images.
When to Use PDF to Images
- Extracting slides — Getting individual PowerPoint or Keynote slides (exported as PDF) as standalone image files.
- Social media content — Exporting pages from a brochure or presentation as images for sharing on social platforms.
- Content preview thumbnails — Generating preview images of document pages for display on a website.
- Editing a PDF page — Converting a page to an image, making edits in an image editor, then converting back to PDF.
- Archiving — Exporting legal or historical documents to image format for long-term archival alongside the original PDF.
How Conversion Works at QuickyDesk
Image to PDF: PyMuPDF creates a new PDF document and inserts each uploaded image as a page sized to the image's pixel dimensions at 72 DPI. Multiple images are added in upload order. The output is a standard PDF with one page per image.
PDF to Images: PyMuPDF renders each page of the PDF at 150 DPI using its built-in rendering engine, producing a PNG file per page. All PNG files are compressed into a ZIP archive for a single download. Page files are named page_1.png, page_2.png, etc.
Tips for Best Results
- For Image to PDF — photograph documents flat. Curved or wrinkled documents cast shadows that reduce readability in the final PDF. Lay documents flat on a desk in good light before photographing.
- For Image to PDF — use PNG for screenshots and diagrams. PNG is lossless and produces sharper text in the output PDF. Use JPG for photographs where the slight compression is acceptable.
- For PDF to Images — 150 DPI is for screen use. At 150 DPI, exported images are suitable for digital viewing, web use, and social media. If you need print-quality images from a PDF page, 150 DPI may not be sufficient — 300 DPI is the standard for print.
- Compress after Image to PDF. Converting high-resolution photos to PDF can produce large output files. Run the result through the Compress tool to reduce size before sharing.
File Requirements
- Image to PDF: JPG, JPEG, PNG — max 50 MB per file, multiple files supported
- PDF to Images: PDF only — max 50 MB, single file
- Password-protected PDFs: Not supported for PDF to Images
Frequently Asked Questions
Which image formats are supported for Image to PDF?
JPG (JPEG) and PNG are supported. Both work well. PNG is preferred for screenshots, diagrams, and documents with text — PNG is lossless and preserves sharp edges. JPG is fine for photographs where a small amount of compression is acceptable.
Can I convert multiple images into one PDF?
Yes. Select multiple image files and they are combined into a single PDF, one image per page, in the exact order you uploaded them. There is no practical limit on the number of images, though very large batches (50+ high-resolution images) may take longer to process.
What resolution are the exported images from PDF to Images?
PDF pages are exported as PNG images at 150 DPI. This is optimised for screen viewing and digital use — suitable for web, email, social media, and presentations. If you need higher resolution for print purposes, 150 DPI may not be sufficient; commercial print typically requires 300 DPI.
How are the exported images from PDF to Images delivered?
All exported images are packaged into a ZIP archive. Each page becomes a numbered PNG file: page_1.png, page_2.png, and so on. Download the ZIP file and extract it to access the individual page images.
Will the PDF page size match my image dimensions?
Yes. For Image to PDF, each image is placed on a PDF page sized to match the image's pixel dimensions exactly. No cropping or padding is added. A 1200×900 pixel image produces a 1200×900 point PDF page.
Can I convert a multi-page PDF to images?
Yes. Every page in the uploaded PDF is exported as a separate PNG image. A 20-page PDF produces 20 PNG files delivered in a single ZIP archive. Processing time increases with page count — a 50-page PDF may take 15–30 seconds to convert.
What is the maximum file size for conversion?
The maximum file size is 50 MB per file for both image-to-PDF uploads and PDF-to-images uploads. If your source PDF exceeds 50 MB, consider splitting it into smaller parts first, converting each part, then merging the resulting images or PDFs.
Can I convert a scanned PDF to images?
Yes. Scanned PDFs are image-based, so each scanned page is exported as a PNG at 150 DPI. The output quality matches the original scan resolution — if the scan was done at high DPI, the PNG will reflect that; if the scan was low-quality, the PNG will reflect that too.
