JPG sa JFIF Mga Madalas Itanong (FAQ) tungkol sa Pag-convert
How do I convert JPG to JFIF without losing image quality?
+
Upload your JPG file and our converter applies format-aware quality optimization for JFIF output. For lossless targets (PNG, TIFF, BMP) every pixel is preserved bit-for-bit; for lossy targets (JPG, WebP) you can tune the quality factor (default 90) before download.
Does JPG to JFIF conversion preserve transparency?
+
Transparency survives when JFIF is PNG, WebP, TIFF, GIF, or SVG. Converting to JPG flattens the alpha channel against a white background — if you need transparency, pick a transparency-aware target instead of JFIF.
Will my colour profile (sRGB / Adobe RGB / CMYK) survive JPG to JFIF?
+
Embedded ICC colour profiles are read from the source JPG and re-attached to the JFIF output where the format supports it (JPG, PNG, TIFF, WebP). Formats without profile support fall back to sRGB with a soft-proof step.
What happens to EXIF metadata when converting JPG to JFIF?
+
Camera EXIF (ISO, shutter, lens, GPS) is preserved by default during JPG -> JFIF when both formats support metadata. Use the privacy toggle to strip metadata before download if you want to share images without geolocation or device-fingerprint exposure.
Can I batch-convert hundreds of JPG files to JFIF at once?
+
Yes — drag multiple JPG files into the upload zone and they queue in parallel. Free tier accepts 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 JFIF compare to Photoshop / GIMP for the same task?
+
For straightforward format conversion we run the same libpng / libjpeg-turbo / libwebp / ImageMagick pipelines a desktop editor uses, at the same quality. The difference is that desktop tools open one file at a time; we accept a batch and run them in parallel on server-side workers.
What resolution and dimensions does the JFIF file have?
+
Default behaviour is 1:1 — your JFIF output has the same pixel dimensions as the source JPG. If you need to resize as part of the conversion, use /resize-image/ after, or chain the operations with the /image-pipeline/ utility.
How small can the JFIF file get without visible artifacts?
+
For JPG / WebP, quality 75-85 typically yields a JFIF 60-80% smaller than the JPG with no visible difference at normal viewing distance. For lossless JFIF (PNG, TIFF), expect smaller savings — usually 5-30% via better deflate / LZW compression than the source already had.
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 retention window is documented at /privacy/.
Does the JPG to JFIF converter work for very large images (50MP+)?
+
Yes for free up to 100 MB. Premium handles much larger inputs (300 MB+) and exotic per-pixel depths (16-bit PNG, 32-bit float TIFF, HEIF 10-bit). The pipeline streams pixel rows so memory use scales with row count, not total pixel count.
Why is my converted JFIF file bigger or smaller than expected?
+
A JPG file with strong compression (heavily lossy JPG) often grows when re-encoded into a lossless JFIF (PNG, TIFF), and a high-bitrate lossless JPG often shrinks dramatically when going to JPG/WebP. The ratio depends on the image content (photos compress differently from line-art or screenshots).
Can I use the converted JFIF file commercially?
+
Yes. The conversion is a format change — copyright on the image content stays with whoever held it on the source JPG. We add no watermark, no metadata stamp, and claim no licence over the JFIF output.
Ang mga file na JPG ay gumagamit ng lossy compression na na-optimize para sa mga larawan, na nagpapakita ng maliit na laki ng file habang pinapanatili ang visual na pamantayan.
