Frequently Asked Questions
What does a PNG file converter do?
A PNG file converter turns JPG, WebP, HEIC, and other inputs into PNG. PNG is ideal for graphics, screenshots, logos, and images that need a transparent background.
What is PNG Effort, and when should I use Fast Mode?
PNG Effort (0–6) controls how hard the optimizer works to shrink a lossless PNG; higher levels can be slower. Fast Mode uses the browser’s native PNG encoder and skips that optimizer for speed. This page defaults Fast Mode on for PNG; uncheck it if you want smaller PNGs via Effort.
Will converting a photo to PNG make it larger?
Often yes for camera photos that were already compressed as JPG—PNG is usually lossless and keeps more detail. Convert to PNG when you need sharp edges or transparency; for everyday photos that must stay small, use Convert to JPG or the WebP Image Converter instead.
Can I batch convert many files to PNG?
Yes. Select multiple images, keep Convert to as PNG, then convert and export as a ZIP. For JPG or WebP batches, use Convert to JPG, the WebP Image Converter, or the full Image Converter.
When should I convert an image to PNG?
Choose PNG for logos, icons, screenshots, charts, and any graphic that needs a transparent background or sharp text edges. Soft camera photos usually work better as JPG or WebP if small file size matters more than lossless detail.
Does this PNG converter keep transparency?
When the source has transparency (or you export overlays that need a clear background), PNG can keep an alpha channel. JPG cannot. If your goal is a round or soft-edge graphic on a colored page, PNG (or WebP) is the right output—not JPG.
