Drop. Check. Keep.
Have a look.
See the new size in the row and compare the copy with its original before you keep it.
Keep the lighter copy.
Save puts it next to the original, named like photo-smally. Smally never replaces your original or any file already there.
What Smally does with a HEIC
Smally opens HEIC photos, but it cannot check a smaller HEIC against its quality rule yet, so it keeps the original HEIC. The row can offer As JPEG, a copy that opens on any computer, phone or website.
Smally makes this copy for photos up to 40 megapixels, including 12-megapixel iPhone photos. If the copy comes out no lighter or cannot be written, it keeps the HEIC and the row says why.
HDR and the honest edges
- HDR photos from an iPhone carry a gain map that lets an HDR display show bright highlights. Smally carries it into the copy when it can, and tells you when it cannot.
- The JPEG is often larger than the HEIC and keeps no date, camera or location. Use it when you need a photo that opens everywhere, not to save space.
- Animated images, other HDR formats, 10- and 16-bit images and CMYK images are skipped, with a sentence that says what to do instead.
Why not in the browser
Smally in the browser does not read HEIC files. Smally for Mac does, and nothing is uploaded.

Questions
Does Smally upload my photos?
No. Smally for Mac works on your Mac, and your files never leave it.
Does the JPEG keep the HDR look?
Smally carries the photo's HDR gain map into the copy when it can, and tells you when it cannot.
Will the JPEG be smaller than the HEIC?
Often not. HEIC is an efficient format, so the JPEG is often larger. As JPEG is for a photo that has to open everywhere.
Does the JPEG keep the date and location?
No. The JPEG keeps no date, camera or location.
How big a photo can it convert?
Smally makes an As JPEG copy for photos up to 40 megapixels, including 12-megapixel iPhone photos.
