Deep dive
What is JPG to PDF?
JPG to PDF combines JPG photos into a single, shareable PDF document — one image per page. It is the fastest way to turn a stack of phone photos into an emailable file, or to build a photo report from a folder of pictures.
FormatSwitch composes the PDF in your browser using pdf-lib, so the source photos never leave your device. The resulting PDF opens on any operating system without extra software.
When to use it
- Convert phone photos of a receipt or ID into a PDF for upload forms.
- Turn scanned pages into a proper multi-page PDF.
- Bundle event photos into a single shareable file.
How to use it safely without uploading
Drop your JPGs, reorder them by drag, and press Convert. Each image becomes one PDF page and the finished document downloads locally.
Browser-based vs server-based conversion
Most online converters upload your files to their servers, process them there, and then let you download the result. That means your file exists on someone else's computer, often in logs and backups, sometimes indefinitely. FormatSwitch is different: every conversion runs on your device using WebAssembly and the browser's built-in Canvas and PDF engines. Your file never leaves your computer, so there is nothing to leak, nothing to subpoena, and nothing to trust us on — the code that does the work is running right in your tab.
FAQ
JPG to PDF — questions people ask
- Are my photos uploaded?
- No. Files are processed entirely in your browser using WebAssembly and the Canvas API. Nothing is uploaded to a server, and no copy is kept once you close or refresh the tab.
- Can I reorder images before conversion?
- Yes. Drag the files in the queue to set the page order.
- Is there a watermark on the PDF?
- Never. FormatSwitch adds no watermark, logo, or quality cap to your output — the file you download is only what your browser produced.
- Does it work on mobile?
- Yes. Every tool runs on modern iOS Safari and Android Chrome. Very large files may be slower on mobile because of tighter memory limits.
- Are the source photos stored anywhere?
- No. Files live only in your browser's memory (JavaScript heap). They disappear when you clear the queue, refresh, or close the tab. There is no server, no database, no log.
- How many images can I combine at once?
- There is no hard image count, but very large batches use more browser memory. On phones, keep batches under a few hundred photos for best results.
