FLAC Cutter FAQ
Does the format limit where I can cut?
+
It does. FLAC is lossless compression — bit-identical to the source on decode, at about half the size of WAV. That is precisely what decides whether a cut can be placed arbitrarily or has to land on a structural boundary.
Anything specific to FLAC when trimming?
+
Yes — FLAC decodes bit-identically to the source, so any number of edit-and-resave cycles cost you nothing in fidelity. It explains most of the "the cut is a fraction of a second off" surprises.
Can I remove a section from the middle instead of keeping one?
+
Yes — cut the piece before it and the piece after it, then merge the two results. That is deliberately two steps because it keeps both halves on the fast, lossless path instead of forcing a full re-encode.
Is the part I keep re-encoded?
+
Not if the format allows a stream copy — the data you keep is bit-identical to the source and the job finishes in about the time the upload took. Only a frame-exact cut on a format that cannot do it cheaply needs a re-encode.
Can I run FLAC Cutter on several FLAC audio files at once?
+
Yes, though lossless files are large, so the batch is bound by upload bandwidth rather than by processing. Settings apply uniformly across the set.
Are bit depth and sample rate preserved?
+
Yes, unless you change them deliberately. A 24-bit/96 kHz source stays 24-bit/96 kHz — nothing is silently downsampled to 16/44.1, which is the failure mode that makes a master unusable.
Does FLAC Cutter cost anything?
+
No. FLAC Cutter is free with no account required, and nothing is added to the audio. Uploads are deleted from the workers shortly after the job finishes.
Is there a file size limit on FLAC Cutter?
+
Yes: free accounts process audio up to 200 MB per file — for uncompressed PCM that is roughly twenty minutes of CD-quality stereo, so it is a real limit here in a way it is not for MP3. If you are over it, converting WAV to FLAC first is the free fix — it is lossless and roughly halves the size.
Why does a PNG site host FLAC Cutter?
+
PNG.to is built around the format you use when you cannot afford to lose a pixel: lossless, alpha-capable, and the correct answer for screenshots, logos, line art and anything with hard edges. Image work is rarely one step: people arrive to change a format and leave needing the picture a different size, a different weight or a different shape. Running FLAC Cutter on the same upload pipeline, the same size caps and the same account is the whole reason it is here rather than on a fourth tab.
What should I do with the result once FLAC Cutter is finished?
+
The converter on this site moves images to and from PNG, JPG, WebP, GIF and SVG — which is the step where the decision about transparency actually gets made. That is the step most people actually came for, and doing it after FLAC Cutter rather than before it means the conversion works from the file you finally settled on.
Is FLAC Cutter here the same tool the sibling sites run?
+
The engines are shared — the same libraries, the same workers, the same limits. What differs is the advice, and the advice here starts from one fact about the format this site is named after: there is no quality slider to get wrong — a PNG round-trips bit-exactly, so the only thing edits cost you is file size. A PNG site is opinionated about where PNG is the right destination and where it is not, and that judgement is worth more than the button.
Do I need an account, and does anything get kept?
+
No account, and nothing is kept: uploads are deleted from the workers shortly after the job finishes, and nothing you process is indexed, listed or used for anything else. Free accounts exist for history and batch size, not for access.
