Best Free JPG to PDF Converters in 2026 — I Tested 4 Tools With 25 Image Sets

ILovePDF (iLovePDF S.L., Barcelona) offers a dedicated JPG-to-PDF converter within its 25+ tool suite. Upload images, drag to reorder, select page size (A4, Letter, or Fit to Image), choose orientation, set margins, and merge into a single PDF or convert each image separately. The interface shows thumbnail previews with smooth drag-and-drop reordering. All processing happens on their servers in Barcelona.

Conversion quality was excellent across all 25 test sets. Images were embedded losslessly — no re-compression artifacts. Page layout options covered most use cases. The drag-and-drop reordering was the smoothest in our test, particularly useful when arranging 15+ receipt scans in the correct order.

The catch: free users get 1 task per hour and a 20-image limit per conversion. Our 50-image product catalog test required splitting into 3 batches on free, which meant 3 hours of waiting. The upload step added 15-30 seconds for high-res image sets. Paid users at $7/month remove these limits.

SmallPDF (SmallPDF GmbH, Zurich) keeps things minimal. Upload images, and they're converted to a single PDF on A4 pages. There's limited page size control and no orientation selector — the tool auto-detects. The interface is clean but offers fewer layout options than ILovePDF or MiOffice AI. All processing happens on Swiss servers.

Single-image and small batch conversions worked well. The output was clean for standard use cases. However, we noticed slight re-compression on high-res images — zooming to 400% revealed JPEG artifacts not present in the originals. The lack of page size options beyond A4 was limiting for our mixed-orientation test sets. Portrait photos on landscape pages left large white margins.

Free tier allows 2 tasks per day. Pro costs $12/month. The 20-image limit per conversion blocked our 50-image catalog test entirely on the free tier.

Adobe Acrobat's "Create PDF" feature handles image-to-PDF conversion with the precision you'd expect from the PDF format's inventor. The online version handles basic conversion; the desktop app offers advanced page layout, OCR text recognition on scanned images, and fine-grained control over image embedding quality. Lossless JPEG embedding preserves every pixel. The desktop app also supports combining images with existing PDFs in a single workflow.

Image quality was perfect — lossless embedding with zero re-compression. Page layout options in the desktop app were the most comprehensive in our test. OCR on scanned receipt images produced searchable text layers, a feature none of the other tools in our test offered during JPG-to-PDF conversion. The online tool was more limited — fewer layout options and no OCR.

The problem: there is no free tier. The online tool requires an Adobe account and pushes you to a 7-day trial, then $19.99/month. For simply converting images to PDF, that's steep.

Img2Go (Online Media Technologies Ltd) is a multi-format conversion platform supporting JPG, PNG, BMP, TIFF, GIF, WebP, and more — all convertible to PDF. Upload images, select page size and orientation, and download the result. The interface is functional but cluttered with ads and upsell prompts on the free tier. Processing is server-side.

Basic JPG-to-PDF conversion worked reliably. Image quality showed slight re-compression on high-res photos, similar to SmallPDF. Page size options were adequate (A4, Letter, Fit to Image). The unique advantage is broad format support — we successfully converted TIFF scans and WebP screenshots to PDF, which some competitors don't handle natively.

Free tier caps at 3 tasks per day and 10 images per conversion. Our 50-image test required splitting into 5 batches across 2 days on the free tier. Ads are prominent and occasionally cover interface elements on mobile.
