PNG→JPG — Frequently Asked Questions

Yes — completely free, with no watermark and no signup required.

Yes, because JPG has no transparency. Transparent areas become white. Use WebP if you must keep transparency while shrinking the file.

Yes. Batch uploads are supported and the results are delivered as a single ZIP.

At our default quality of 90, the loss is invisible for photographs. JPG discards only detail the eye struggles to see. For graphics and text, though, PNG stays sharper — convert those only if size really matters.

JPG cannot store transparency, so transparent areas are flattened onto a white background. If you need to keep transparency, stay with PNG or convert to WebP instead.

Yes. Upload a whole batch and every file is converted, then bundled into one ZIP for a single download.

Neither. The tool is completely free, with no account and no watermark on your images.

No. Any blocky noise already baked into the JPG stays in the PNG, because the artifacts are now part of the pixels themselves. PNG simply stops any further loss from future edits.

No. A JPG has no transparency to carry over, so the PNG starts fully opaque. You then erase or mask the background yourself in an editor, which PNG can store once you do.

PNG is lossless, so it keeps every pixel exactly rather than discarding detail the way JPG does. Larger size is the trade-off for an editable, non-degrading file.

Yes. Upload a batch and each JPG is re-encoded as its own PNG, then delivered together so you only download once.

Lossless. The image looks pixel-for-pixel identical afterward; only redundant data, unused palette entries, and surplus metadata are removed. Transparency is fully preserved.

Photographs are full of subtle gradients with little repetition, so lossless compression finds almost nothing to remove. Convert such images to JPG or WebP instead for a real size cut.

No. The alpha channel is kept intact, which is the whole point of staying in PNG rather than converting to a format like JPG that drops transparency.

Yes. Upload several at once and each is optimised independently, then bundled so a single download gives you all the smaller files.

Yes. Unlike JPG, WebP supports a full alpha channel, so transparent and semi-transparent areas of your PNG carry over intact while the file gets much smaller.

Commonly half the size or less for transparent graphics, and even more for photographic content, because WebP uses modern prediction and transform techniques PNG lacks.

All current browsers display WebP, but some legacy email clients and older desktop software still expect JPG or PNG. Convert to JPG for those specific cases.

WebP can be either lossy or lossless. This converter balances strong compression with sharp edges, so transparent graphics stay crisp while photographic detail compresses efficiently.

Resizing changes the image's pixel dimensions; compression changes how tightly those pixels are stored. Shrinking an oversized image is usually the most effective way to cut file size.

Scaling down keeps an image sharp because it discards excess pixels you were not seeing. Blur only appears if you scale a small image up, which adds no real detail.

Yes. The longest edge is capped at the target and the shorter edge scales to match, so the picture stays perfectly proportioned and never looks stretched.

Yes. The resizer accepts PNG, JPG, and WebP inputs, scaling each down to a web-friendly maximum dimension while preserving its original aspect ratio.
