JPG · PNG · WebP · reorder & rotate · stays on this device
Privacy: images are read only in this tab’s memory. Nothing is uploaded to our servers. Soft limits: ~12 MiB per image, ~48 MiB / ~40 images per batch — large phones may struggle. HEIC is not supported in this MVP.
How it works
- You pick JPG, PNG, or WebP files. Bytes stay in browser memory.
- Reorder with ↑↓, rotate 90°, or remove pages you do not need.
- Choose Fit, A4, or US Letter, set margins, adjust photo quality if needed.
- Convert with pdf-lib in this tab — not a server. Open DevTools → Network: you should see no image upload.
We do not offer remote URL fetch, cloud storage, OCR, e-sign, or password-protected PDFs in v1. Bring files you already have and have the rights to use.
Limits (honest)
- Formats: JPG, PNG, WebP. HEIC/HEIF rejected or skipped — not marketed here.
- Memory-bound: phones and low-RAM tabs may fail on large batches.
- Quality slider: honest re-encode control for photos; not a “target under N MB” guarantee.
- Non-goals v1: OCR, e-sign, password PDF, HEIC, compress-as-hero, merge existing PDFs.

FAQ
Are my images uploaded?
No. Conversion runs in your browser. Open DevTools → Network while you work: you should see no upload of your image bytes. Files never leave this device.
Which formats work?
JPG/JPEG, PNG, and WebP in the MVP. HEIC/HEIF is not supported here (convert first elsewhere if needed). We do not market HEIC conversion.
Can I reorder or rotate pages?
Yes. Use ↑↓ to reorder, rotate 90°, or remove a page before downloading the PDF. Page size options: Fit to image, A4, or US Letter, plus margins and a quality slider for photos.
Is there a size limit?
Honestly: yes, your device's memory. Soft guidance is about 12 MiB per image and about 48 MiB / ~40 images per batch. Very large photos may be slow or fail on phones. We do not claim unlimited cloud processing.
Do you offer OCR, e-sign, or password PDF?
No in v1. LocalImgPdf focuses on images → PDF. Merge existing PDFs belongs on a PDF merger; OCR and e-sign are out of scope.
Is it free?
Yes. No account and no watermark in the MVP.
