Frequently asked questions

What does PNG to ICO do?

Build a Windows .ico from an image, with every size you tick in one file.

When would I actually use this?

Meeting a requirement: a PNG where transparency matters, a JPEG where size does, a WebP for the web, or a specific DPI for print.

What is the most common mistake?

Converting a JPEG to PNG to improve it. PNG is lossless, so it preserves the compression damage already present and produces a much larger file for no gain — the loss happened at the first save.

How is PNG to ICO different from ICO to PNG?

They sit next to each other but answer different questions: ICO to PNG is the one to open when you need it to pull every image out of a Windows icon file and save them as PNGs. Pick whichever matches what you're starting from — both are free.

Is there a tool for the next step?

JPG to PNG is the closest one after this: Convert JPG/JPEG images to lossless PNG.

Where do the figures come from?

Conversion uses the browser's own encoders. Changing DPI rewrites a metadata field only — it does not resample the image, so the pixel data is untouched and the print size changes without any loss.

ComparisonJPEG, PNG, WebP or AVIF: Which Format, and WhyTwo properties decide the format — photographic or flat-toned, and whether it needs alpha or animation. Everything else is downstream. With measured byte counts for the same two images in all four formats.How-toConverting Between PNG and JPG Without Losing What MattersThe two directions fail in opposite ways. PNG to JPG silently flattens transparency onto a background colour the converter chooses — we got white from one tool and black from another on the same file. JPG to PNG recovers nothing and cost up to 11.4 times the bytes.ExplainerDPI, PPI, and What Actually Controls Print SizeThe DPI figure inside an image file is a label. It changes no pixels. Printed size is pixels divided by PPI — and DPI, properly used, means something else entirely: the printer's dots.GuideFavicons: What Sizes You Actually Need in 2026Five files cover every consumer that exists: the tab, the bookmark, the pinned tile, the Android home screen and the iOS home screen. The twenty-file lists are a dead browser matrix — with measurements showing what a 16-pixel icon can and cannot hold.ExplainerStripping Photo Metadata: What Actually Comes OffA JPEG can carry six separate metadata blocks, not one. We built a file holding all of them — coordinates, camera serial, a hidden thumbnail, XMP, IPTC, a comment — pushed it through the cleaner, and read the output byte by byte to see what survived.ComparisonWebP vs JPG vs PNG: Which Image Format Should You Use?JPG, PNG and WebP each win in different cases. Here is when to use each for the best balance of quality, file size and compatibility.
