Estimated time
Plan for 8-12 minutes to prepare images, review a preview, and export a polished PDF.
Why this is useful
- Consolidate multiple JPG files into a single, paginated document that prints consistently.
- Reduce accidental edits by sharing a read-only PDF instead of loose images.
- Apply consistent margins, orientation, and sizing so every page feels intentional.
- Send a lightweight file that opens on any device without extra viewers.
- Use a privacy-first, online tool with no installation or account required to start.
Step-by-step: convert JPG to PDF with Dexify
- Gather your images. Place all JPGs in one folder and rename them in the intended sequence (01-cover.jpg, 02-diagram.jpg). Clear naming keeps page order predictable.
- Launch the tool. Open the Dexify JPG to PDF page in your browser. No installation or sign-in is needed to start a conversion.
- Upload files. Drag and drop one or many JPGs. For large batches, stay on stable Wi-Fi to upload faster.
- Check orientation. Rotate any sideways images before exporting. Portrait pages should stay portrait; wide diagrams belong in landscape.
- Choose page size. Select A4 or Letter to match your printing region. Keep margins between 0.25 and 0.5 inch for balanced whitespace.
- Pick fit mode. Use ?fit to page? for full-bleed visuals or ?center with margin? to avoid clipping edges. For scans, centering prevents cropped signatures or stamps.
- Review order. If thumbnails are visible, drag them to reorder. Otherwise rely on the numeric file names you set earlier.
- Preview quality. Zoom to 150% and scan a few pages. Text in photos should remain legible and lines should stay sharp.
- Export and download. Click convert to generate the PDF. Dexify processes locally when possible, so your source files stay private.
- Verify the output. Open the finished PDF, scroll through, and confirm page order, margins, and clarity before sharing it.
Prepare images for best results
Start with images in sRGB color for universal viewing. Aim for 150-300 DPI; extremely high resolutions inflate file size without noticeable gains on screens. If you are scanning documents, clean smudges and align pages before capture to minimize edits later.
When collaborating, agree on a naming convention like 01_intro.jpg to avoid accidental reordering. Keep a small margin on forms that require stamps or signatures so nothing important is clipped at the edges.
Tip: A simple preflight checklist prevents rework. Confirm file names, orientation, and margin settings before you click convert.
Real-world use cases
Education
Combine whiteboard snapshots, textbook excerpts, and lab diagrams into a single PDF handout. Students get one file that prints cleanly and reads well on mobile.
Business and sales
Bundle product mockups, annotated screenshots, and signature-ready pages into a polished sales packet. PDFs preserve layout and reduce the need for client-side tools.
Legal and compliance
Convert exhibits, site photos, and labeled diagrams into paginated PDFs with predictable numbering. Clear sequencing speeds up reviews and keeps evidence tidy.
Personal and creative
Create photo albums, recipe cards, or art proofs that are easy to store, print, and share. A single PDF means no lost files or mismatched sizes.
Quality tips and best practices
- Use even lighting when capturing documents to reduce glare and color shifts.
- Keep file names short and numeric to avoid ordering mistakes during upload.
- Choose landscape pages only when the content demands width; mixed orientations can feel jarring.
- Enable moderate compression if the PDF is large. Avoid over-compressing text-heavy images to prevent artifacts.
- Store a copy of the original JPGs in case you need to adjust contrast or crop before re-exporting.
- Add a short cover page if your set is long; it helps recipients know what is inside.
Troubleshooting and common pitfalls
- Blurry output: Start from higher-resolution images and avoid repeated exports. Check that ?fit to page? is not stretching small images excessively.
- Pages look cropped: Increase margins or switch to center-with-margin mode. Confirm that landscape images are not forced into portrait.
- File size is too big: Reduce DPI for non-critical images, enable balanced compression, or split a very long set into two PDFs.
- Wrong order after export: Rename images with numeric prefixes and re-upload. Avoid relying on drag order alone for very large batches.
Conclusion and next steps
Converting JPG to PDF is straightforward when you prepare filenames, pick sensible margins, and preview before exporting. Dexify keeps the process online, fast, and private so you can deliver a professional document in minutes.
