PNG na JPG Často kladené otázky o konverziách
How do I convert PNG to JPG for the modern web?
+
Drop your PNG file into the picker and our encoder produces a JPG output tuned for web delivery: quality factor 80 by default (a Lighthouse sweet-spot), correct color space, and an Accept-aware fallback you can ship behind a `<picture>` element alongside the original PNG.
Will JPG actually be smaller than PNG?
+
Almost always when going from PNG / JPG / TIFF into WebP or AVIF: expect 25-50% smaller than JPG at the same visual quality, 60-90% smaller than PNG. Going the other way (WebP / AVIF back to JPG = PNG / JPG) typically grows the file because you are leaving a more modern codec for an older one — useful for compatibility, not size.
Does PNG to JPG preserve transparency / alpha?
+
Transparency survives when JPG supports alpha (PNG, WebP, AVIF, GIF, TIFF, SVG). Converting to JPG flattens the alpha channel onto white — if you need transparency on the modern web target WebP or AVIF instead of JPG.
Can I keep my color profile (sRGB / Display P3) going from PNG to JPG?
+
Yes for JPG formats that store ICC profiles (PNG, JPG, WebP, AVIF, TIFF). Modern wide-gamut profiles like Display P3 round-trip through WebP and AVIF; sRGB profiles round-trip through every common JPG. If JPG cannot store a profile, output is tagged sRGB to keep browsers from guessing.
What lossy vs lossless quality settings does the JPG encoder support?
+
Lossy JPG (WebP / AVIF / JPG) accepts a quality 1-100, default 80. Lossless JPG (PNG / WebP lossless / TIFF) does not take a quality dial — every pixel is preserved. WebP and AVIF are the only formats that can do either, which is why they are ideal JPG targets when source PNG mixes photos and graphics.
Will the JPG version look identical to the PNG on a Retina display?
+
At quality 80+ on WebP / AVIF the difference is invisible to anyone but a trained eye even at 3x device pixel ratio. Photos compress slightly more visibly than line art; if your PNG is screenshots or UI mockups, push quality to 90 or use a lossless JPG.
Does PNG to JPG keep animation frames?
+
Animated PNG (animated WebP, GIF, APNG) survives only when JPG is also animation-aware (animated WebP, GIF, APNG). Converting an animated PNG to a static JPG (PNG, JPG, AVIF still) yields just the first frame — use a dedicated animation converter if you need to keep all frames.
Will EXIF camera metadata survive PNG to JPG?
+
Yes by default when both PNG and JPG support EXIF (JPG, PNG, WebP, TIFF, HEIC). Camera fields (ISO, shutter, lens, GPS) are copied through. Use the "strip metadata" option if you are publishing to the web and want to drop GPS coordinates before JPG leaves your browser.
Can I batch convert a folder of PNG files to JPG?
+
Yes — drop multiple PNG files at once and they encode in parallel. Free accounts: 100 MB per file. Pro accounts get more parallel workers and bigger per-file caps, so a 200-image gallery typically finishes in well under two minutes.
Are my PNG files private during JPG conversion?
+
Yes — uploaded PNG files are processed in isolated workers and deleted within minutes. No human reviews the pixels, no copy is retained, no third party gets a feed. See /privacy/ for the precise retention window.
How do I serve the JPG with a PNG fallback on my site?
+
Use a `<picture>` element: `<picture><source srcset="image.JPG" type="image/JPG"><img src="image.PNG" alt=""></picture>`. Browsers that understand JPG fetch the smaller file; older browsers fall back to PNG. WebP is supported in 96%+ of installed browsers, AVIF in 90%+.
Why is my JPG file unexpectedly bigger / smaller than I expected?
+
A PNG that is already heavily compressed (low-quality JPG) often grows when re-encoded into a lossless JPG (PNG / TIFF). A high-bitrate lossless PNG (PNG / TIFF) often shrinks 60-90% when going to a lossy modern JPG (WebP / AVIF). Image content matters too — photos compress very differently from line art and screenshots.
