JPEG Quality Filter

WordPress recompresses your images at 82% — change it

Quality

What it does to a flat graphic

A hard edge on a flat colour is the worst case for JPEG. Drag the slider and watch the halo appear around the shapes. This is rendered live in your browser at the exact quality you picked.

Only affects images uploaded AFTER the filter is active. Existing images keep the quality they were encoded at until you regenerate them. And note the preview above is your browser's JPEG encoder, not your server's — the artefacts are representative, the byte counts are not.

Tungkol sa JPEG Quality Filter

Every JPEG you upload is re-encoded at quality 82 by default. That is fine for photos and visibly bad for screenshots and flat graphics. This generates the filter to change it, with a live preview of what each quality level costs.

FAQ

Mga Tanong

Anong JPEG quality ang ginagamit ng WordPress bilang default?

82. Bawat JPEG na ina-upload mo ay muling ine-encode sa quality na iyon, at gayundin ang bawat derivative size na binubuo ng WordPress mula rito. Makatwirang default ito para sa mga larawan at nakikitang mahina para sa screenshots, logos at flat graphics — mayroon silang hard edges at walang photographic noise na maitatago ang compression artefacts.

Dapat ko bang itakda ang JPEG quality sa 100?

Hindi. Sa itaas ng humigit-kumulang 92 ay bumibili ka ng file size sa halip na nakikitang quality, at kayang triplehin ng 100 ang file para sa pagkakaibang walang makakapansin. Kung screenshots o UI graphics ang iyong images, 88–92 ang makatwirang saklaw.

Naaayos ba ng pagbabago nito ang mga image na na-upload ko na?

Hindi. Ang filter ay tumutugon sa mga image na na-process pagkatapos itong maging aktibo. Pinapanatili ng existing na image ang quality kung saan sila na-encode hanggang sa muli mong i-upload sila o mag-regenerate ng thumbnails gamit ang isang plugin o 'wp media regenerate'.
