Can I Convert Multiple Files at Once?

The current jpg.now interface is designed around single-file conversions- You upload one image, choose your output format, and download the result. The one exception is JPG-to-PDF, which accepts multiple images and merges them into a single multi-page document. True batch conversion of independent files is on the roadmap.

Single-File Workflow

For all conversions other than JPG-to-PDF, upload one file per conversion. The process is fast enough that converting a handful of files sequentially is practical within the daily conversion limit.

Multi-Image PDF: The One Batch Exception

The JPG to PDF converter accepts multiple JPG files in a single upload. Each image becomes one page in the output PDF, in the order you arrange them. This is the only converter that currently supports true multi-file input.

Planned Batch Mode

A general-purpose batch converter is planned for a future release. It will allow uploading many files at once and converting them all to the same output format, with a single ZIP download. No firm release date has been announced; signing up for a free account is the best way to be notified when it launches.

Workarounds Right Now

Use a desktop tool such as ImageMagick (mogrify) for true local batch conversion.
On macOS, the built-in Preview app can export multiple images by selecting them all and using File → Export.
On Windows, IrfanView has a free batch conversion feature under File → Batch Conversion.
