LocalJPG vs CloudConvert
Do you need to upload to convert?
tl;dr
CloudConvert is a powerful server-based platform that supports 200+ formats and API automation. LocalJPG converts HEIC and WebP to JPG in your browser with zero uploads. Choose CloudConvert for format variety and developer workflows; choose LocalJPG for privacy and one-off photo conversion.
CloudConvert is a serious conversion platform — ISO 27001 certified, used by developers and enterprises. But “certified secure” still means your files travel to their servers. LocalJPG takes a different approach: the conversion happens entirely on your device, so certification is irrelevant — there is nothing to certify.

The privacy difference
CloudConvert is ISO 27001 certified and deletes files after 24 hours. These are real security controls. But ISO 27001 certifies the management system around data — not the absence of data. Your file still travels to a server, gets processed, and sits there until the TTL expires.
LocalJPG doesn't have a security policy for file storage because there is no file storage. The conversion runs inside your browser via libheif and MozJPEG, compiled to WebAssembly. Open DevTools → Network before dropping a file — you will see analytics pings, but zero image data in transit.
When CloudConvert is the better choice
CloudConvert supports over 200 file formats — documents, video, audio, ebooks — not just images. If you need to convert a PDF, a .docx, or a video file, LocalJPG cannot help. CloudConvert also has a robust API for automated workflows and a generous free tier for occasional use. LocalJPG is purpose-built for HEIC and WebP to JPG — and does that one job without uploading anything.
Frequently asked questions
Is CloudConvert safe to use?▾
CloudConvert has ISO 27001 certification, SSL encryption, and a clear deletion policy (files deleted after 24 hours). For most use cases it is considered safe. For sensitive personal photos — medical, legal, personal — a zero-upload tool like LocalJPG eliminates the risk entirely.
How many free conversions does CloudConvert offer?▾
CloudConvert's free tier provides 25 conversion minutes per day, roughly 10 image conversions. LocalJPG allows unlimited single-file conversions for free with no daily cap.
Does LocalJPG support as many formats as CloudConvert?▾
No. LocalJPG converts HEIC, HEIF, and WebP to JPG — that is it. CloudConvert supports 200+ formats including documents, video, and audio. If you need format variety, CloudConvert or a similar server-based tool is the right choice.
Which is cheaper for batch photo conversion?▾
LocalJPG charges $5 once for any batch ZIP, with no per-conversion pricing and no account. CloudConvert charges by conversion minutes — $8 for 100 credits, each image conversion consuming roughly 1 credit. For occasional photo batches, LocalJPG's flat $5 is cheaper. For high-volume or automated workflows, CloudConvert's subscription tiers make more sense.
