JPG to PDF Free — Batch Convert Images Online
Convert JPG to PDF free online. Batch upload, drag to reorder, page size & quality control. No signup, no watermark, browser-based.
Key Features
- Multi-file upload — add up to 100 JPEGs in a single session, drag-to-reorder before conversion
- No-re-encode embedding — original JPEG bytes are placed in the PDF without decoding and re-encoding (no quality loss)
- EXIF orientation handling — photos taken on phones with 90°/180°/270° rotation are automatically corrected
- Four page size presets — A4, Letter, Legal, A3 — plus custom width/height in mm
- Margin control — zero margin (image fills page) or standard margins (image within printable area)
- Rotation per-image — click any thumbnail to rotate 90° clockwise before building the PDF
- Portrait and landscape auto-detection — matches page orientation to image aspect ratio by default
- Runs fully in-browser — photos never leave your device
About JPG To PDF
JPG to PDF converts one or more JPEG images into a single PDF document — handling reorder, rotation, margin, page size (A4, Letter, Legal, A3, custom), and compression all in the browser without uploading files. Upload multiple JPGs, drag to reorder them into any sequence, rotate any that arrived landscape when they should be portrait, and choose whether each image fills the page edge-to-edge or sits within margins. The conversion uses pdf-lib's JPEG embedding, which preserves EXIF orientation data and does not re-encode the JPEG (no generation loss).
The key difference from basic JPG-to-PDF tools is the no-re-encode guarantee. Most online converters decode your JPEG to pixels and re-encode to JPEG again during PDF creation, adding compression artifacts on every round-trip. This tool embeds the original JPEG bytes directly into the PDF image stream — what you see on screen is exactly what the PDF renderer draws. The resulting file size is also smaller because the JPEG stays at its original compression ratio rather than being optimized again by an unfamiliar encoder.
Who Uses This Tool
- Students scanning handwritten notes or homework and combining into one PDF to submit
- Professionals assembling photographed receipts into a single expense report PDF
- Real estate agents compiling property photos into a PDF slideshow for clients

- Small businesses sending multi-page signed paper forms as a single PDF via email
How to Use JPG to PDF Free — Batch Convert Images Online
- Step 1: Drop one or more JPGs into the upload area. Thumbnails appear immediately in order.
- Step 2: Drag thumbnails to reorder pages. Click any thumbnail's rotate button to fix orientation. Remove unwanted images with the X on each thumbnail.
- Step 3: Choose a page size (A4 is the international default; Letter for US print). Set margins if you want white space around the image.
- Step 4: Click Convert to PDF. pdf-lib embeds the JPEGs and assembles the document. For 20 images this typically takes under 3 seconds.
- Step 5: Download the PDF. Open it to verify page order and orientation before sending or printing.
Frequently Asked Questions
Does converting JPG to PDF reduce image quality?
No, if you use this tool. The original JPEG bytes are embedded directly in the PDF without re-encoding. Other tools that convert pixel-by-pixel and re-compress can degrade quality slightly on each round-trip. This tool preserves the original compression.
What is the maximum number of images I can add?
The tool handles up to 100 images in a session, limited by browser memory. Very high-resolution images (16MP+ from DSLR cameras) at 100 images could approach 1GB of RAM — for very large batches, split into groups of 20-30 images.
Can I convert PNG or WEBP images to PDF with this tool?
This specific tool is optimized for JPEG. For PNG, WEBP, GIF, BMP, or TIFF, use the Image to PDF tool which handles all formats. The conversion is identical except PNG files are re-encoded to JPEG for PDF embedding (JPEG is the native PDF image format — PNG requires lossless PNG filtering which makes PDFs larger).
Why does my phone photo appear sideways in the PDF?
Phone cameras embed orientation in the EXIF metadata but save pixels as landscape regardless. This tool reads the EXIF orientation and corrects the display. If a photo still appears rotated, use the per-image rotation button on the thumbnail to fix it before converting.
Can I add more images after starting the conversion?
Yes — click Add More after uploading and drag-and-drop more JPGs. They append to the end of the list. Reorder by dragging before clicking Convert to PDF.
