Save a verified JPEG/JFIF image with a .jpg filename while preserving the original compressed bytes and metadata.
Drag and drop one or more files, or choose files from your device.
Supported: .jfif, .jpg, .jpeg · up to 10 sources · 20 MiB per source. Existing codec, duration, pixel and memory limits apply.
Existing marker/decode checks followed by byte-for-byte JPEG export. No resizing, metadata rewrite, recompression or automatic rotation.
Enter your values locally; no inputs are uploaded.
Check validation feedback before reviewing the browser-generated result.
Review the explanation, copy supported outputs or reset the workspace.
Choose one supported local file, review the conversion settings, select Convert and inspect the verified output before downloading. No. JFIF describes a JPEG interchange convention, commonly stored with .jfif or .jpg extensions. Compatible files already contain JPEG-compressed image data.
Save a verified JPEG/JFIF image with a .jpg filename while preserving the original compressed bytes and metadata. JFIF is a JPEG interchange convention, not a separate codec. Compatible JPEG input is validated using SOI/EOI markers, frame dimensions and actual decoding, then exported byte-for-byte without recompression. No resize or re-encode mode is applied. Valid JPEGs need not contain a JFIF APP0 marker. Unusual JPEG coding modes, damaged files and trailing data after EOI are rejected.
Your file bytes, pixels, SVG content and filename remain in browser memory. They are not uploaded to a conversion server, saved by this tool or included in page analytics. Clipboard and downloads require explicit actions. Reset clears pending processing and owned preview URLs; ordinary page requests may still be logged.
No. JFIF describes a JPEG interchange convention, commonly stored with .jfif or .jpg extensions. Compatible files already contain JPEG-compressed image data.
No. The default and only export path preserves the original bytes. Decoding is performed only to validate that the JPEG can be read, not to generate replacement compressed pixels.
Yes, in the byte-preserving path the compressed data and metadata remain identical to the accepted source. The converter verifies byte-for-byte equality before offering the .jpg download.
It must be a genuine compatible JPEG with SOI and terminal EOI markers, a supported frame header, bounded pixel dimensions and successful browser decoding. The extension or declared MIME type alone is not sufficient.
No. This tool intentionally performs a byte-preserving interchange-name conversion. Stored pixel dimensions and orientation metadata remain unchanged; the browser preview can apply orientation metadata when displaying it.
JPEG files can use other valid metadata conventions, including Exif. The converter checks the actual supported JPEG structure and decodability rather than requiring one optional interchange marker.

Processing is browser-only with bounded input size, decoded pixels, output bytes and operation time. Files larger than 20 MiB, individual images above 16 MP or batches above 40 million frame/page pixels are rejected. SVG has a tighter 2 MiB source limit. These limits protect responsiveness; they do not imply universal codec support.
