No — converting to PNG won't restore detail that JPEG already discarded when the photo was first saved. What it does do is stop any further quality loss on future saves. PNG is lossless, so every subsequent open-and-save keeps the pixels exactly as they are. If you're editing a JPEG repeatedly, convert to PNG first so you're not stacking compression artefacts on top of each other.
Those are JPEG block artefacts caused by the 8×8-pixel grid the codec uses to compress data. They get worse each time you re-save at a lower quality setting. To prevent more: always export from the original high-quality source rather than re-saving an already-compressed file. To recover: if you no longer have the original, converting to PNG preserves what's left without adding new artefacts, but it can't un-blur detail that's already gone.
For web use, 75–85% quality hits the sweet spot — files are 3–5× smaller than 100% with almost no visible difference on screen. For print or archival use, stay at 90–95%. Going below 70% saves a little extra space but introduces visible noise on fine details like text, hair, and fabric texture.
Not directly — JPEG has no alpha channel, so transparency is impossible in that format. To get a transparent version: convert to PNG or WebP first (both support full transparency), then use PortImg's Remove Background tool to strip the background. The whole process takes under a minute.
