Convert HEIC to a JPEG that fits your limit
Select your file, choose JPG, then set the target required by your destination. Processing happens in the browser. HEIC support depends on the file and the browser decoder. The conversion library loads when first needed. If decoding fails, export a JPEG with a compatible image application and try that file.
Check the converted file
Conversion changes the encoded image; it is not a filename change. Download and reopen the result, check exact bytes and dimensions, and inspect important detail. Large inputs or tight caps may reduce dimensions. Keep your original because metadata and other source features are not preserved.
Targets use 1024 bytes per KB when the binary checkbox is checked and 1000 when unchecked. A success badge confirms the selected ceiling, not every requirement of an upload form.
