Both. Lock the ratio and one dimension is derived from the other, which is what you want almost always. Unlock it and you get exactly the numbers you typed, at the cost of stretching — useful for a fixed slot, wrong for a photograph.

Match the slot it will live in. A full-width web hero rarely needs more than 1920 pixels wide, a content image 1200, a thumbnail 400, and doubling those numbers covers high-DPI screens. Anything beyond that is bytes nobody sees.
Kodi Kusintha kwa PNG imasintha bwanji ma dimensions?
+
Concretely, pixels ndi resampled ndi Lanczos wochotsa ndi kulemba m'mbuyo losslessly, choncho chokha inu kuwononga ndi deta kuti mwamsanga sangakhale m'malo m'ma pixels pang'ono; palibe kuwonjezera ndi encoder pa pamwamba.

Kodi ndingagwiritse ntchito Kusintha kwa PNG pa PNG images angapo nthawi imodzi?
+
Yes — kutsitsa set ndi iwo kusonkhana mofanana pansi pa imodzi set of settings. Lossless owona ndi zikuluzikulu, kotero lalikulu gulu ndi kugwirizana ndi kutsitsa wanu galimoto kuposa ndi kusonkhana yekha.
Kodi Kusintha kwa PNG imawononga chilichonse?
+
No. Kusintha kwa PNG imayenda mwaulere popanda akaunti ndipo siyiwonjezera madzi. Fayilo imachotsa ntchito za ogwira ntchito pambuyo poti mutsitsa, ndipo palibe chilichonse chokhudza chithunzicho.

PNG, BMP ndi TIFF ndi mafomu a raster osatha omwe amagwira ntchito moyenera, ndipo mabungwe othamanga (JPG, WebP, GIF) amagwira ntchitonso ngati mukufuna kuwagwiritsa ntchito pamodzi. TIFFs osiyanasiyana amapezeka ndikuyang'aniridwa patsamba ndi tsamba.
Kodi Kusintha kwa PNG idzachepetsa mtundu wa PNG images wanga?
+
Sichoncho. A lossless kuchokera round-trips bit-exactly, kotero ngati inu mosabisa akufuna kwa lossy kutulutsa mtundu pixels amene anabwerera ndi pixels amene anapita mu. Izi ndi chifukwa chakuti zonse kutsatira ntchito mu izi banja pamene inu mwakhala kusinthira.
Kodi Kusintha kwa PNG ikupezeka patsamba lokhudza mtundu wa chithunzi?
+
JPEG.to ndi yopangidwa m'munsi mwa mtundu womwe umabweretsa pafupifupi chilichonse cha zithunzi zomwe zilipo - zaka makumi atatu, zotsegulidwa ndi zonse, komanso zomwe zilipo bwinobwino kwa chithunzi cha zithunzi. Ntchito zomwe anthu amabweretsa pano ndi zomwe zithunzi zimasonkhanitsa m'moyo wake - zochuluka kwambiri kuti zitumize imelo, zosayenera zosayenera za form, zosayenera zosayenera zosayenera. Kusintha kwa PNG imagwira ntchito pamodzi ndi kutsitsa ndi akaunti yomweyo monga kusintha chifukwa ndi komwe ntchitozi zimatha.
Kodi ndi chiyani choyenera kutsatira pambuyo pa Kusintha kwa PNG?

The Converter pa iyi sitemo amasintha zithunzi kuti ndi kuchokera JPEG, PNG, WebP ndi HEIC, amene ndi pamene malonda pakati pa kukula kwa fayilo ndi m'badwo wina wa kuwonongeka amapeza anaika. Kusankha mtundu waposachedwapa kuposa koyamba ndi chinthu chofunikira: chilichonse chowonjezera chopulumutsa chithunzi cha zithunzi ndi chiyambi china, ndipo zochulukirapo zomwe mumagwiritsa ntchito, zithunzi zambiri zimatha kupulumuka.
Kodi ndi ichi chimodzimodzi injini monga ena converter malo?
+
Yes - mabuku omwewo, ogwira ntchito omwewo, ma caps omwewo. Kusiyana ndi zomwe zidziwitso zili patsamba, ndipo pano zomwe zidziwitso zimapangidwa pamodzi ndi mtundu wa mtundu womwe umagwiritsidwa ntchito: the.jpeg ndi.jpg zowonjezera ndi chimodzimodzi bitstream, choncho palibe apa amachita mosiyana ndi.jpg — zosintha zokha za dzina la fayilo.
