Quick start: JPG to PDF in under a minute

Open JPEGtoPDF.io.
Add images from your phone or computer.
Drag to reorder pages and rotate if needed.
Choose page settings and quality options.
Convert and download your PDF.

This works for merge JPG to PDF, JPEG to PDF, and mixed image formats.

Supported formats and when to use them

JPG/JPEG: Best for photos and small file size.
PNG: Better for screenshots, text-heavy images, and sharp edges.
WEBP: Compact web format with good quality.
HEIC/HEIF: Common on iPhone; support depends on browser capabilities.

If your goal is a readable document, prioritize clear source images before tuning compression.

Settings explained

Images per page: Place 1, 2, or 4 images per page when you need to combine multiple photos efficiently.
Page size and orientation: Choose A4, Letter, Legal, or other sizes with Portrait/Landscape based on your target use.
Margins and background: Use margins for print-safe spacing and background color for consistent page presentation.
Fit vs Fill: Fit keeps full images visible. Fill crops edges to remove borders.
DPI: Higher DPI improves print sharpness. Lower DPI reduces final PDF size.
Compression: Controls the quality/size tradeoff. Medium values usually work best for sharing.
Strip metadata: Removes EXIF data to improve privacy and reduce output size.
Output mode: Use Single PDF for one combined file, or One per image for individual files.

How to keep quality high and file size low

Use source images that are in focus and well-lit.
For email-friendly files, start around 120 to 144 DPI.
For print-ready documents, use 200 to 300 DPI.
Increase compression gradually until quality is acceptable.
Strip metadata for smaller files and better privacy.

Device-specific tips

iPhone and iPad

Use Safari for the smoothest experience. If HEIC previews are inconsistent, retry with fewer files or convert to JPG first.

Android

Use Chrome and your system file picker. For large batches, convert in smaller groups for better stability.

Desktop (Mac/Windows/Linux)

Drag-and-drop folders or multi-select files for the fastest workflow.
