PSD to JPEG for social and IM handoffs: assume the platform will recompress and anchor QA on downloaded bytes, not chat thumbnails
WeChat, Slack, Teams, and mail clients almost always re-encode attachments and show tiny previews, so “blurry in the thread” often does not mean your bytes are wrong. Pages like `psd-jpeg-export-online` are meant to turn a signed-off PSD into a compact sRGB JPEG with explicit intent while documenting that inline previews are not authoritative. Put long edge, quality, and ICC embedding rules in the brief, attach guidance to download the original file for review, and you will cut false escalations where design is blamed for platform behavior.
Cómo utilizar
- Before upload, confirm the canvas is sRGB 8-bit or document the intended transform, hide every non-delivery layer, and note in the ticket if ICC embedding is forbidden to save bytes—otherwise someone may retag the file later without a paper trail.
- Open the downloaded JPEG in the OS viewer and directly in Chrome or Safari at the same crop; do not judge sharpness from IM previews alone or you will misdiagnose platform recompression as a failed conversion.
- Ship versioned filenames and state “this attachment is the QA source”; when many ad sizes are needed, freeze quality and resampling templates, then spot-check one size against the flattened PSD composite so every channel is not tuned ad hoc.
PSD to JPG (jpeg) FAQ
Lightweight JPEG for marketing—should we embed ICC profiles?
Most social and performance ads assume sRGB pixels; embedding an ICC profile adds a few kilobytes to tens of kilobytes and may violate strict channel specs. More important than the toggle itself is writing “deliver sRGB, do not retag” into the ticket or README so ops cannot silently resave through a viewer that rewrites metadata and later leaves no accountable trail.
JPEG shows banding in gradients—is quality too low?
Often on skies and ramps; raise quality, reconsider subsampling, or add tiny dither in PS first—also rule out 8-bit display banding.
Small type looks softer in JPEG than PNG—why?
JPEG hurts high-frequency detail. Split live type to vector handoff or locally boost quality/sharpen for text blocks.
Many ad sizes from one master—how do we keep JPEG params aligned?
Freeze quality, color space, and resampling templates with shared version suffixes; spot-check one size against the flattened PSD.
Chat previews are blurry but originals look fine—is conversion wrong?
Instant messengers generate low-res previews and often apply another lossy pass, so a fuzzy bubble does not prove the attachment is fuzzy. Validate the file users get after tapping “download original” or by opening the object-storage URL in a browser, and add one sentence to the email body that IM thumbnails are not acceptable for sign-off—this single habit prevents a lot of unfair design escalations.
