"PowerPoint can't read the file".
PowerPoint said it can't read your presentation and offered no repair at all. Upload the .pptx and see the watermarked slides recovered from a rebuilt copy. A one-time $14 USD — and only if the repair works. In the small measured set, slide content was recoverable, but no complete presentation container was recovered.
Free preview — pay only if you download ($14 USD)

We couldn't recover this one.
The file is too damaged to rebuild, so there is nothing to preview and no charge.

Try a deep repair
The repair engine can try a longer pass on the file you already uploaded.
Machine-only processing; no human views files; nothing is sent to an outside AI.
Have another clip from the same device?
A healthy video recorded on the same device — ideally the same settings — gives the repair engine a template to rebuild from. It can unlock repairs that fail on their own.
Unrepaired files are kept encrypted for up to 30 days, then deleted.
FileFix can't fix that kind of file yet.
Right now we repair video, audio, document, and image files (MP4, MOV, M4V, MKV, AVI, TS, MTS, M2TS, MPG, MPEG, VOB, 3GP, WebM, FLV, M4A, WAV, MP3, AAC, FLAC, OGG, OPUS, AIFF, XLSX, DOCX, PPTX, ODT, ZIP, RAR, PDF, AI, HEIC, and HEIF). We're adding support for more formats over time.

Why this happens
"Can't read the file" usually means PowerPoint failed earlier than a content problem — it could not treat the file as a valid package at all, so it never got as far as offering to repair anything.
The most common cause is damage at the very start of the file. A .pptx is identified by a ZIP signature in its first bytes; when a truncated download, a failed sync, or a partly overwritten file destroys those bytes, every tool that checks the signature first will refuse the file, no matter how much intact slide data sits behind it.
FileFix does not require the signature to be at the start. It searches the uploaded bytes for the package parts themselves, rebuilds a valid .pptx around whatever slides it can parse, and validates the result. This is the case where a file that opens in nothing at all still produces a usable watermarked preview.
What we can and can't recover
We can usually fix
- Presentations that show "PowerPoint found a problem with content"
- Presentations PowerPoint offers to repair and then fails on
- Presentations cut off mid-save or mid-transfer
- Files whose first bytes were wiped, so nothing will open them
We can't fix
- Password-protected/encrypted presentations
- Genuinely empty (0-byte) files
- Deleted or formatted files (that's data recovery, a different job)
- The old binary .ppt format (this repair is for .pptx)
How it works
-
Upload Drop the file in. It uploads over an encrypted connection. The repair runs automatically — no person looks at your file.
-
Free watermarked preview You see exactly what we recovered — watermarked slides and the recovered slide count.
-
Pay & download If the preview shows what you need, unlock the repaired presentation for a one-time $14 USD.
You see a watermarked preview built from your actual file before you decide anything — so you never guess.

Questions
PowerPoint may be unable to recognize the presentation as a valid ZIP package, especially when the opening signature or package records were damaged by a truncated download, failed sync, or partial overwrite.
Yes. Individual slide XML parts can remain in the bytes even when the package wrapper is unusable. FileFix searches for those parts and builds a fresh presentation around the slides it can parse.
The free preview shows watermarked slides from the rebuilt presentation and the recovered slide count before checkout.
A one-time $14 USD — and only if the repair works. Seeing what was recovered is free, and checkout is only offered when the engine produces a validated repaired file.
