How do I convert JPG to JPEG without losing image quality?
+
Upload your JPG file and the converter applies format-aware quality optimization for the JPEG output. For lossless targets (PNG, TIFF, BMP) every pixel is preserved; for lossy targets (JPG, WebP, AVIF) you can tune the quality factor before download.
Does JPG to JPEG conversion preserve transparency?
+
Transparency survives when going to PNG, WebP, TIFF, GIF, or SVG. Converting to JPG flattens the alpha channel against a white background — if transparency matters for your use (web overlays, logos), target a transparency-aware format instead of JPEG = JPG.
Will my colour profile (sRGB / Adobe RGB / CMYK) survive JPG to JPEG?
+
Embedded ICC colour profiles are read from the JPG source and re-attached to the JPEG output where the format supports them (JPG, PNG, TIFF, WebP). Formats without profile support fall back to sRGB. Print-shop CMYK workflow round-trips correctly through TIFF and high-bit JPG.
What about EXIF metadata when converting JPG to JPEG?
+
Camera EXIF (ISO, shutter, lens, GPS coordinates) is preserved by default during JPG → JPEG conversion when both formats support metadata. Use the privacy option to strip metadata before download if you want to share images without revealing geolocation or capture device.
Can I batch-convert hundreds of JPG files to JPEG at once?
+
Yes — drag multiple JPG files into the upload zone and we queue them in parallel. Free users get up to 100 MB per file; Premium has no per-file cap and runs more parallel workers, so a 200-image batch typically finishes in under two minutes.
How does JPG to JPEG compare to Photoshop or GIMP for the same task?
+
For format conversion we run the same libpng / libjpeg-turbo / libwebp / ImageMagick pipelines a desktop editor uses, with identical output quality. The difference is workflow — desktop tools handle one file at a time; we accept a batch and run them in parallel server-side.
What resolution and dimensions will my JPEG file have?
+
Default behaviour is 1:1 — your JPEG output has the same pixel dimensions as the JPG source. To resize as part of the conversion, use /resize-image/ before or after this step. Chaining is faster than re-rendering at a new size inside the conversion pipeline.
How small can the JPEG file get without visible artifacts?
+
For JPG / WebP, quality 75-85 typically yields a file 60-80% smaller than the source JPG with no visible difference at normal viewing distance. For lossless targets (PNG, TIFF), expect modest savings — usually 5-30% via better deflate / LZW compression than the source happened to use.
Are my JPG files private during conversion?
+
Yes — uploaded JPG files are processed in isolated workers and deleted within minutes. We never read, store, or share the pixel data. The full privacy policy and retention window are documented at /privacy/.
Does the JPG to JPEG converter work for very large images (50 MP and up)?
+
Free up to 100 MB per file. Premium handles larger inputs (300 MB+) and exotic per-pixel depths (16-bit PNG, 32-bit float TIFF). The pipeline streams pixel rows, so memory use scales with row count not total pixel count — a 100-megapixel image converts at the same memory footprint as a 10-megapixel one.
Why is my converted JPEG file bigger or smaller than I expected?
+
A JPG file with strong existing compression (heavily lossy JPG) often grows when re-encoded to a lossless JPEG (PNG, TIFF); a high-bitrate lossless JPG often shrinks dramatically going to JPG / WebP. The ratio depends on image content — photographs compress very differently from line art or screenshots.
Can I use the converted JPEG file commercially?
+
Yes. The conversion is a format change only — copyright on the image content stays with you (or whoever held it on the JPG source). We add no watermark, embed no tracking pixels, and claim no licence over the JPEG output.
