PNG files accommodate transparency and use lossless compression, making them ideal for graphics, logos, and screenshots.
Common Uses
Creating logos and graphics with transparent backgrounds
Saving screenshots and digital artwork
Web graphics requiring transparency
PNG Transformation FAQ
What is a PNG file?
+
PNG is a lossless raster image format that stores every pixel without compression artifacts. PNG is well-suited to screenshots, line art, illustrations with hard edges and any image that will be further edited.
Is anything lost when a PNG is converted to another lossless format?
+
No pixel data. PNG stores the image exactly rather than approximating it, so a conversion between two lossless formats is reversible and can be repeated indefinitely without degradation. What can be lost is everything around the pixels — colour profiles, transparency, animation, embedded metadata — because support for those varies far more between formats than the pixel storage does. PNG uses DEFLATE compression over filtered scanlines, so every pixel survives exactly, plus a full 8-bit alpha channel.
Why did my screen recorder save a PNG?
+
Because it is the format the recorder's platform encodes natively, so capture costs almost no processing while the machine is busy doing something else. It is a sensible choice while recording and an awkward one afterwards — the file usually needs converting before it can be shared, edited or embedded anywhere outside the system that made it. PNG was designed in 1996 as a patent-free replacement for GIF, and became the web’s default lossless image format.
Does PNG keep a transparent background?
+
Yes — the format stores a real alpha channel, so cut-out logos, product shots and overlays keep their transparency instead of arriving on a white rectangle. Converting to a format without alpha is where it goes wrong: the transparent areas are filled with a solid colour, usually white or black, and there is no way back short of masking the subject again. PNG is the right choice for screenshots, logos, line art and anything with hard edges or transparency — no ringing, no colour banding.
Can I use PNG directly on a web page?
+
Yes — every current browser renders it natively, so it needs no fallback copy and no conversion at publish time. The remaining question is weight rather than support: the same picture in a modern web format is frequently a third of the size at the same visible quality, which is worth doing on anything that appears above the fold.
Who controls the PNG format?
+
Nobody, and that is the point of it. The specification is public, anyone may implement it without asking or paying, and no company can change the terms later — which is why archives, standards bodies and public institutions specify formats like this one for anything that still has to open in twenty years. The trade is not compatibility, which is excellent; it is that there is no vendor to call when some tool implements the spec badly.
Can I just rename the extension instead of converting PNG?
+
Almost never, and it is worth understanding why: the extension is a label, while the bytes inside are structured for one specific format. Renaming produces a file whose name promises something its contents do not deliver, and whatever opens it either refuses the file or misreads it. The one narrow exception is two formats that are genuinely the same container under different names — and even then a proper rewrap is safer than a rename.
Can I convert a whole folder of PNG files in one go?
+
Yes — drop them in together and they are queued as one job rather than converted one at a time, with the same settings applied across the batch and the results returned together. Free accounts run a couple concurrently; a paid plan lifts both the concurrency and the per-file size limit, which is what makes converting a large archive practical.
When should I convert PNG to another format?
+
Convert PNG to JPG or WebP when the target context is the open web or email, where smaller file size matters more than per-pixel fidelity. PNG is a poor photograph format: a photo saved as PNG is routinely five to ten times larger than the same image as JPG or WebP.
Will converting PNG reduce image quality?
+
When you convert PNG to another lossless format the pixels are preserved exactly. When you convert PNG to a lossy format such as JPG the encoder makes quality-vs-size trade-offs you control via the output quality setting.
