PowerPoint recovery options and guides.
FileFix recovers PowerPoint (.pptx) presentations that won't open or show “PowerPoint found a problem with content”. Upload the presentation and see a free summary of the recovered slides with a short excerpt of their text before you pay; you pay only if it shows what you need.

We couldn't recover this one.
The file is too damaged to rebuild, so there is nothing to preview and no charge.
What stopped you continuing? One tap tells us why.
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 PowerPoint presentations stop opening
A .pptx presentation is a ZIP package. Each slide is a separate XML part under ppt/slides, and a content-types list plus a web of relationship files tells PowerPoint which part is which. PowerPoint checks that surrounding structure before it shows you a single slide.
An interrupted save, a cut-off download, or a damaged archive index can break that structure while the slide XML itself is still sitting in the file. Sync clients and USB drives that are pulled mid-write are common causes. PowerPoint then refuses the whole presentation, or offers to repair it and fails.
FileFix works from the surviving ZIP records rather than the package index. It recovers the slide parts it can parse, rebuilds the content types and relationships around them, and writes a fresh valid .pptx. It then reopens that result independently before generating a preview.
The watermarked preview shows slides from the rebuilt presentation and the recovered slide count. It verifies recovered text; it does not promise that layouts, themes, images, animations, transitions, speaker notes, or embedded media survived.
You never install anything, and you don't create an account to try it. You upload, you view the watermarked preview, you decide.
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
A .pptx is a ZIP container of XML parts. FileFix scans the readable members, recovers the slide XML it can parse, rewrites the package relationships and content types, and verifies that the result opens as a presentation.
It shows watermarked slides from the rebuilt .pptx and the recovered slide count. The preview is a limited sample of the recovered presentation.
The repair is built around recovered slide XML. The preview verifies recovered slide text, not layouts, themes, images, animations, transitions, speaker notes, or embedded media. Do not assume those survived unless you inspect the downloaded presentation.
No. This repair handles .pptx files. The older .ppt format uses a different binary structure and is not processed by this engine.
No. FileFix does not remove passwords or bypass encryption. The engine must be able to read the slide XML to repair it.
PowerPoint needs the ZIP package, its content types, and its relationships to be consistent before it will open a presentation. Individual slide XML parts can remain readable even when that surrounding structure is damaged. FileFix rebuilds a valid package around the slides it can still read.
Not necessarily. A .pptx whose leading bytes were destroyed will be rejected by PowerPoint and by most tools, because the ZIP signature is read from the start of the file. FileFix looks for the package parts further in, so a file that opens nowhere else is still worth uploading.
A one-time $14 USD — and only if the repair works. The watermarked preview is free, and checkout is unavailable when the engine cannot create and validate a repaired .pptx.
No. The file is processed automatically, including the watermarked preview. Originals of repaired files are kept encrypted only until your repaired file is deleted, at most 2 days after you pay, then deleted; unrepaired files are kept encrypted for up to 30 days, then deleted.
No software is required to upload or run the repair. You will need PowerPoint, Keynote, Google Slides, or another compatible app to inspect and use the downloaded .pptx.
It tells you how many slides the rebuilt presentation contains, in presentation order. Use the preview and the count together as evidence of what was recovered rather than as a guarantee that one particular slide is intact.
Yes, on a copy. If PowerPoint's "Repair" button produces a usable file, you avoid an upload entirely. FileFix is the separate path for when that prompt fails or loops.
No. FileFix creates a separate repaired presentation. It does not overwrite the source file on your computer or phone.
