  3. Press Convert (or switch to Compress) and download.

Private by design

Boltly runs entirely in your browser. Your files are processed on your own computer and are never uploaded, so it is safe for IDs, contracts and family photos, and it keeps working offline once loaded.

Questions

Will the images be stretched?

No. Each image keeps its aspect ratio and is scaled so its longest side fits the size you choose.

Are my images uploaded?

No. Everything runs in your browser.
