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.

A matsayin diff, na'am, duk inda manufar take da wani wuri don sanya shi - nau'in kamara, daidaitattun nunawa, linzamin kwamfuta da GPS coordinates duk suna daukewa. GPS shine filin da ya cancanci tunani: idan hoton zai kasance an wallafa shi, amfani da zaɓin metadata-strip don haka ba ka daukewa inda hoton aka dauka. WebP ne Google na 2010 image format, gina daga VP8 keyframe encoder da kuma nufin su maye gurbin JPG, PNG da GIF a lokaci guda.

Firam na farko kawai zai tsira, saboda PSD wani nau'in tsari ne mai tsayawa da ba da wurin adana sauran ba. Idan motsi yana da muhimmanci, ka yi niyya ga wani nau'in tsari wanda ke motsi, ko kuma ka canja zuwa wani kontener na bidiyo a maimakon haka ka riƙe motsin.
