Convert JPG, PNG and HEIC images to a single PDF

Five concrete differences: (1) Pricing — Adobe Acrobat Pro is $19.99/mo with mandatory Adobe ID sign-in even on the free online JPG-to-PDF tool, plus the free tier limits you to 2 conversions before forcing the 7-day trial; Smallpdf gates the free tier at 2 tasks per day across all 21 tools, then $9/mo Pro for batch; iLovePDF caps free at 20 images per batch then $9/mo Premium; Canva Pro is $14.99/mo to remove watermarks; pdfFiller is $20/mo Premium after a 30-day trial; CamScanner forces account creation and stamps an ad watermark on free; jpg2pdf.com is genuinely free but caps at 20 files and 5 MB per file with 60-min server retention. iFillPDF is fully free with no card and no signup, no batch cap, no file-size cap. (2) HEIC iPhone support — only iFillPDF natively decodes ISO/IEC 23008-12 HEIF/HEIC (the iPhone default since iOS 11) via libheif WebAssembly; Adobe accepts only JPEG/PNG/BMP/GIF/TIFF; iLovePDF requires Premium $9/mo for HEIC; jpg2pdf.com does not support HEIC at all. (3) Privacy — Adobe processes on AWS us-east-1 under Cloud Act 50 USC §3024 + FISA 702; Smallpdf hosts in Switzerland outside EEA (no automatic GDPR adequacy); iLovePDF on Spanish servers; pdfFiller and CamScanner on US AWS; jpg2pdf.com retains uploads for 60 minutes. iFillPDF runs PDF-lib + WebAssembly entirely in your browser — your photos never leave the device under GDPR Art. 4(2). (4) Metadata — only iFillPDF strips EXIF GPS coordinates, camera serials and date stamps client-side before binding (critical for journalists, brokers, lawyers handling FRCP Rule 34 discovery). Adobe Acrobat online preserves EXIF by default, leaking GPS into PDFs shared by email. (5) Standards — iFillPDF outputs ISO 32000-2:2020 PDF 2.0 with preserved ICC color profiles (Adobe RGB 1998, sRGB IEC 61966-2.1) and optional ISO 19005-2 PDF/A-2 archival for IRS 26 USC §6001 retention.

Yes — iFillPDF natively decodes ISO/IEC 23008-12 HEIF/HEIC (the default iPhone format since iOS 11, September 2017) via libheif BSD-licensed compiled to WebAssembly. Drop your .heic files straight from the Photos app via AirDrop, USB-C transfer or iCloud Photos download — no need to open Photos.app and re-export as JPEG (which silently downsamples 10-bit HEIC to 8-bit JPEG, losing dynamic range). Also handles HEIF live-photo extraction (we use the still frame), HDR HEIC with 10-bit color depth, and burst-mode HEIC sequences. Adobe Acrobat online accepts only JPEG/PNG/BMP/GIF/TIFF (no HEIC); iLovePDF requires Premium $9/mo for HEIC; jpg2pdf.com does not support HEIC. The only US-facing free competitor with native HEIC is HiPDF, but it caps at 5 MB per file and uploads to a server.

No upload. Conversion runs entirely in your browser via PDF-lib (MIT-licensed, used by 4M+ npm downloads/week) and WebAssembly libheif — your photos never leave the device under GDPR Article 4(2) (no data transfer = no processing by iFillPDF). You can verify by opening Chrome DevTools Network tab during conversion: zero requests to ifillpdf.com domains. EXIF GPS coordinates, camera serial numbers, lens model, owner name, IPTC copyright tags and date/time stamps are also stripped client-side before binding — critical for journalists protecting sources, real-estate brokers sharing listing photos, and lawyers handling FRCP Rule 34 ESI discovery. By contrast, Adobe Acrobat online preserves EXIF by default (your home address GPS leaks into every shared PDF), Smallpdf and iLovePDF retain uploads for up to 2 hours on their EU/CH servers, jpg2pdf.com retains for 60 minutes, and CamScanner has been flagged by Kaspersky for embedding the Necro trojan in 2019 Android builds. If you upgrade to Start ($8.99/mo) for cloud-saved PDFs and shared workspaces, hosting moves to Hetzner Falkenstein eu-central-1 under TADPF Trans-Atlantic Data Privacy Framework with AES-256-GCM at rest, TLS 1.3 in transit, SOC 2 Type II, ISO 27001:2022 — zero Cloud Act 50 USC §3024 / FISA 702 / Executive Order 14086 exposure.

No strict cap. Because conversion runs client-side via WebAssembly, the only limit is your device RAM — typical M1 MacBook Air (8 GB RAM, Chrome 124) handles 100+ iPhone 15 Pro 48MP HEIC photos in under 8 seconds, and a 200-image batch from a Canon EOS R5 45MP RAW-converted-to-JPEG completes in under 30 seconds. There is no per-file size cap (we have tested 80 MB TIFFs from Hasselblad H6D-100c at 100MP without issue). By contrast: jpg2pdf.com caps at 20 files plus 5 MB per file; iLovePDF free caps at 20 images per batch (then Premium $9/mo for unlimited); Smallpdf caps at 2 free tasks per day across all 21 tools; Adobe Acrobat online does not publish a documented per-batch cap but enforces a 100 MB total upload limit. For batches above 200 images we recommend splitting into 2 passes and using our PDF Merge tool afterward — both run client-side and chain in under a minute.

Yes — and this is the core scan-to-PDF use case for US accountants, freelancers and small businesses. Snap photos of paper IRS Form W-9, receipts for IRS Schedule C Profit-and-Loss deductions, signed NDAs, lease agreements or 1099-NEC backup with your iPhone or Android camera, AirDrop or USB-transfer them to your laptop, drop them into iFillPDF and you get one tidy ISO 32000-2:2020 PDF 2.0 in under 10 seconds. With Start ($8.99/mo) you can enable optional OCR via Tesseract 5 LSTM (80+ languages including English, Spanish, Chinese, Arabic, Hindi) to produce a searchable ISO 19005-2 PDF/A-2 archival file — ideal for IRS 26 USC §6001 retention (3 years for individual returns, 7 years for substantial omissions, indefinite for fraud), 17 CFR §232.302 SEC EDGAR filings, HIPAA 45 CFR §164.316(b)(2) 6-year medical retention, Companies Act 2006 §388 UK statutory archives, and EU Accessibility Act 2025 (Directive 2019/882) WCAG 2.2 AA-tagged PDF/UA-1 ISO 14289-1 for screen-reader compliance. Print-grade fidelity at 300 DPI thanks to preserved ICC color profiles (Adobe RGB 1998, sRGB IEC 61966-2.1). For a polished perspective-correction + auto-deskew workflow on phone-snapped paper, pair iFillPDF with Microsoft Lens or Apple Notes built-in document scanner before drop.
