LIMITS
File and Conversion Limits
ImageConvert uses browser safety limits so conversion stays responsive, honest and private when possible. Limits protect your device from oversized images, huge batches and unsupported workflows.
Batch and engine safety limits
A batch can contain up to 50 files totaling exactly 1 GiB of selected source files. Files are processed strictly one at a time. Server workflows use temporary request storage and delete files after success, error, timeout, disconnect or coordinated shutdown.
Files can still be refused by authentic format checks, dimensions, pixels, frames, duration, structural complexity, available disk, memory or CPU, timeout or engine support; there is no smaller arbitrary source-file cap.
Workflow-specific limits
Animated GIF/APNG files are refused on static-output routes so animation is not lost silently. Pentax K-x PEF 12-bit 3:2 and Samsung NX200 SRW 12-bit 3:2 are additionally qualified for the same four isolated server exports, up to 64 MiB and 24 MP. Only those full-sensor models/variants; no embedded-preview fallback. Sigma DP1 X3F TRUE three-plane HI is additionally qualified with a separate isolated DP1-only LibRaw fork and complete prevalidation; other Sigma models and variants are refused. Named CR2/NEF/ARW/camera DNG/CR3/ORF/RW2/RAF to JPG/JPEG, PNG and WEBP use an isolated non-root LibRaw server worker and temporary request storage. Only the disclosed camera models and variants are qualified. Other RAW inputs remain guide-only with no upload. Rendered LinearRaw DNG output is a separate writer, not camera input. No embedded JPEG fallback or browser RAW decoding. Other specialist routes remain disabled until their exact decoder and output path are byte-proven.
Conversion guide routes remain informational until the required decoder/export path is ready.
