Mai Juyawa WebP zuwa PSD

No. The compression artifacts already baked into the WebP are ordinary pixel data now, and PSD preserves them perfectly rather than removing them. The file usually gets larger, sometimes several times larger. It still worth doing before editing, because further edits will not stack a second generation of loss on top. PSD yana riƙe da duk wani shawara na gyara mai sakewa, wanda shi ne dalilin da ya sa shi ne babban siffar don aikin zane wanda za'a sake shi. WebP har yanzu yana da darasi na biyu a waje na mai bincike - shirye-shiryen aiki na bugawa, da manyan gine-ginen ofishin da wasu galere na wayar ba su yarda da shi ba.
