Capabilities
Everything a converter should do, and nothing it shouldn't.
01
Drag, drop, reorder
Sort items by dragging their thumbnails. Delete, rotate, or clear with a single click. The queue is yours.
02
A4, Letter, Legal, Auto
Pick a standard page size or let Auto fit each page to its image. Portrait or landscape, with adjustable margins.
03
Truly private
Files are processed in your browser. No upload, no server, no analytics on your content. Disconnect from the internet mid-conversion — it still works.
04
Built for volume
Up to 100 images per PDF, up to 100 pages per PDF. Memory-aware rendering with sequential garbage collection prevents browser crashes.
05
ZIP download
Render a PDF to JPG and download every page as a single ZIP archive, or grab individual pages as needed.
06
Mobile-ready
A responsive workspace that adapts from desktop dashboard to phone screen. Touch-friendly thumb actions on every preview card.
How it works
Four steps, no account, no waiting.
01
Pick a direction
Switch between JPG → PDF and PDF → JPG using the tab at the top of the workspace.
02
Add your files
Drag and drop into the upload zone, or click to browse. File validation rejects anything the engine can't handle.
03
Tune the output
Set page size, orientation, margin, fit — or render scale, compression and naming for PDF → JPG.
04
Convert & download
Hit convert. The file is generated in your browser and downloaded instantly. No email, no queue.
Frequently asked
Practical questions, plain answers.
Are my files uploaded to a server?
No. Every byte of processing happens in your browser using JavaScript. Your images and PDFs never leave your device. You can disconnect from the internet after the page loads and the converter will still work.
What's the maximum number of files I can convert?
Up to 100 images per PDF for JPG → PDF, and up to 100 pages per PDF for PDF → JPG. Beyond that, browsers become unreliable with memory — so the cap is enforced before conversion starts.
What file formats are supported?
For JPG → PDF: JPG, JPEG, and PNG. PNG preserves transparency. For PDF → JPG: any standard PDF file, including password-free encrypted PDFs.
Why is the page loading slowly?
The first load fetches four libraries (jsPDF, pdf.js, JSZip, SortableJS) from a CDN. After that, the page is cached by your browser and works offline. Conversion itself is fast — typically under a second for 20 images.
Will this work on my phone?
Yes. The layout collapses to a single column on screens below 980px, and touch-friendly thumb actions appear on every preview card. Modern mobile browsers handle 50-page PDFs without issue.
Can I reorder images after uploading?
Yes. Drag any thumbnail to a new position in the grid. The page order in the final PDF reflects the on-screen order exactly.
