How we compared them
We make BatchSet, so read this with that in mind. To keep it fair, every number for the other five tools comes from that company's own site: pricing pages, tool pages, help articles, and the file limits each tool page loads. If a site does not state a number, the table says "Not stated" instead of guessing.
All of it was checked on October 14, 2026. Prices are in US dollars as shown that day. We did not upload test files to the other services, so the watermark column reports what each site says, not an output test.
BatchSet's numbers come from the same config that enforces them in the app, so they change when our plans change.
Limits and price
The first thing that stops a bulk job is the batch size or the daily allowance. Here is what each tool allows for free.

Privacy, formats and watermarks
Two tools convert inside your browser, so the images never leave your device. The other four upload your files and delete them later; each states its own deletion window below.

- A mixed batch into JPG, including HEIC and camera RAW: iLoveIMG (30 files per task free).

- Unusual formats or files close to 1 GB: CloudConvert or Convertio, within 10 free credits a day.
Converting iPhone HEIC photos in bulk
iPhones save photos as HEIC, which many sites and Windows apps still reject. BatchSet's HEIC to JPG converter decodes them in your browser, free and in batches. A photo that couldn't be read in your browser can be converted on our servers for 1 credit with a free account.
Among the others, iLoveIMG and CloudConvert convert HEIC to JPG, TinyPNG returns HEIC uploads as JPG, and Convertio converts HEIC to most formats. Squoosh has no HEIC decoder of its own.
