Crop PNG FAQ
Does my source format change how a crop behaves?
+
It can. PNG is lossless DEFLATE with a full 8-bit alpha channel and optional 16-bit depth, so it never degrades on re-save but gets large on photographic content. That decides whether the crop is a pure pixel operation or whether the file has to be rebuilt around it.
Anything specific to PNG worth knowing before I crop?
+
Yes — there is no quality slider to get wrong — a PNG round-trips bit-exactly, so the only thing edits cost you is file size. That is the sort of detail that only shows up after you have overwritten the original.
What is the most common mistake when cropping PNG images?
+
Cropping before resizing. Crop first from the full-resolution original, then resize the result — doing it the other way round means the region you keep has already lost detail it did not need to lose.
Can I run Crop PNG on several PNG images at once?
+
Yes — upload the set and they process in parallel under one set of settings. Lossless files are larger, so a big batch is bound by your upload speed rather than by the processing itself.
Does the alpha channel survive?
+
Yes. PNG and TIFF carry a full 8-bit alpha channel and it is preserved end to end. It is only flattened if you deliberately target a format that has no alpha, in which case transparent pixels are composited onto white.
Is there a file size limit on Crop PNG?
+
Yes: free accounts process images up to 5 MB each; lossless sources hit that ceiling sooner than photographs do, because nothing has been thrown away yet. If you are over it, converting to PNG first is often enough on its own — a BMP is routinely ten to twenty times the size of the identical image as PNG.
Why does a Word site host Crop PNG?
+
WORD.to is built around the editable end of a document's life — the DOCX that is still being written, still being styled and still being argued over, before anyone flattens it for sending. Office files are containers full of other people's media — images, embedded audio, fonts — so the work people need on them is usually the work they would need on those contents anyway. Crop PNG shares the upload, the caps and the account with the conversions for that reason.
What should I do with the result once Crop PNG is finished?
+
The converter on this site takes documents out to PDF for sending, to images for embedding and to plain text for anything that has to read them programmatically, and back the other way. Doing that afterwards keeps the editable original around, which is the part you cannot get back once it has been flattened.
Is Crop PNG here the same tool the sibling sites run?
+
The engines are shared — the same document toolchain, the same workers, the same limits. What a Word site adds is a view on what survives leaving the Office format and what does not, which is the question every one of these jobs actually turns on. It also starts from one fact about the format this site is named after: the document is a zip of XML, so text edits are cheap and the weight is almost always the embedded images.
Do I need an account, and does anything get kept?
+
No account is needed. Uploads and results are kept for about 24 hours, which leaves time to download the result, and are then deleted automatically; nobody reads, lists or indexes them. Several files in one job need a paid plan.
