JPG to PDF with no upload — local batch for photos and scans

Convert images to PDF with no upload: drop JPGs, PNGs, or WebPs, reorder, pick page size, and we render a PDF with pdf-lib in your browser — zero file uploads. Perfect for receipts, IDs, or phone scans that should never transit a cloud. Check DevTools: no image leaves your device.

Works offline after first load. Batch 20 photos into one PDF for email — one download, no server queue. Close the tab and only your PDF remains.

PNG, WebP, and GIF too — when to use each

JPG: Best for photographs and scans — smaller. PNG: Keeps transparency and crisp line art — larger, use for screenshots with text. WebP: Modern, small — we convert to embed. GIF: Animated frames flattened to first image (we preserve visible frame locally). If you mix formats, EncloDoc handles each locally — no cloud re-encode.

Tip: After batching, compress without uploading if your image PDF exceeds portal caps. Need PNG only? Use PNG to PDF — no upload or Image to PDF as superset — same local engine.

Page size and quality tips for image PDFs

Pick A4 for printing, Original for photo ratio, or Fit to keep the smallest file. We embed each image at its native quality — no cloud re-encode to 72 dpi. If the image PDF exceeds 5 MB for portals, compress after: compress without uploading — still local. For PNG line art, prefer PNG input to keep text crisp; for phone photos, JPG is smaller. Check DevTools: batch 20 JPGs — zero file uploads, PDF built in memory.

Batch tip: 20 phone scans at 3 MB each become ~60 MB images; embedding locally yields a ~58 MB PDF — then compress without uploading to 5 MB for portals. All in the browser; compare to upload-based JPG→PDF where 60 MB of receipts cross the wire. Check DevTools: batch 20 JPGs — zero file uploads, PDF built in memory. For PNG line art, prefer PNG input to keep text crisp; for phone photos, JPG is smaller.

FAQ — JPG to PDF
No. Selected JPG, PNG or WebP images are embedded locally — each image becomes one PDF page in this tab. Ezgif and Smallpdf upload; EncloDoc reads via the File API and assembles the PDF with pdf-lib locally. You can verify by turning on DevTools → Network before adding images — no image bytes are sent. Works after the page loads even in airplane mode for this flow.
Drop JPG/JPEG, PNG, WebP — multi-select supported — then drag thumbnails to reorder (each image = one page). Choose page size A4, US Letter or Auto per image, plus orientation and margins before you click Generate. The output is a single PDF (e.g. 6 images selected → 6 pages) ready to email or print. No watermark on export — compare smallpdf's free tier limits.
JPG→PDF is optimized for photographs and compressed photos (best for receipts, scans, listing shots). PNG→PDF preserves transparency and lossless graphics (logos, screenshots) and keeps PNG's exact colors. Image→PDF accepts any supported format in one go. If you need mixed types, use Image to PDF; for JPG-only batches this dedicated page is fastest. This separation explains the three URLs.
Currently JPG, JPEG, PNG, WebP; HEIC/TIFF/AVIF can be converted first via your photo app then fed here (HEIC→JPG locally preserves quality, then JPG→PDF). Large stacks work until device memory is hit — a phone handles dozens, a desktop hundreds. Free tier up to 100 MB total, no account; Day Pass covers heavier photo-to-PDF jobs without upload or watermark.
