PPT to TIFF API
POST /v2/convert/ppt/to/tiff returns the visible slides of a .ppt as frames of a single TIFF. With ImageResolution=96, the sample's five 4:3 slides arrive as eastgate-pantry-orientation.tiff: 960 × 720 frames, LZW-compressed, 225,807 bytes, tagged 96 DPI.

Parameters
Send these as form fields next to the file. Names are case-insensitive. If you set one of the documented options below that we don't support yet, the request fails with a 400 that names it instead of returning a file made without it.
| Parameter | What it does |
|---|---|
ImageResolutioninteger, default 150 | Pixels per inch, recorded in each frame when you send it. 96 gives 960 × 720 frames; the default 150 gives 1,500 × 1,125 frames in a 375,523-byte file whose resolution tags say 1 with no unit.Values: 36–600 |
MultiPageboolean, default true | false splits the answer into -1.tiff to -5.tiff. Those files are not compressed: 2,073,834 bytes each at 96 DPI, against 225,807 bytes for all five slides combined. |
PageRangestring | Visible slides to put in the file. 2-3 gave a two-frame TIFF of 105,919 bytes; one slide alone is returned as an uncompressed single TIFF.Values: e.g. 2-3, 4 |
ConvertHiddenSlidesboolean, default false | Include hidden slides as frames; the sample then has six frames in 256,343 bytes. |
ColorSpaceenum, default default | At 96 DPI, monochrome on slide 2 alone gave an uncompressed one-channel TIFF with only black and white pixels, 691,398 bytes. The multi-page file follows it too: its five frames took 122,376 bytes in gray and 32,570 in monochrome, one channel each. rgb returns the same three-channel file as the default.Values: default, rgb, gray, monochrome |
ImageWidthinteger | Frame width in pixels instead of a resolution, with ImageHeight for the height.Values: 1–20000 |
Passwordstring | No help for encrypted decks yet: a locked .ppt returned 422 "the input file is password-protected" with the correct password too. |
What carries over, and what doesn't
Kept
- Slide order and a frame per visible slide, all in one file
- Lossless pixels, LZW-compressed in the multi-page file: 375,523 bytes for the five slides at 150 DPI, where five PNGs take 541,903
- The resolution you ask for, written to every frame
- Color frames stored as three-channel RGB, with no alpha channel
- Vector-sharp charts and text at any resolution; the floor-plan picture keeps its own 480 × 300 pixels
Lost or not yet supported
- Compression when the answer is one slide or
MultiPage=false: a 150 DPI slide alone is 5,062,758 bytes. - Speaker notes and hidden slides by default.
Limits
- Up to 2,000 slides per request; frames up to 16,000 pixels per side and 100 million pixels.
- Requests up to 10 MB on the Free plan or 100 MB on paid plans, and 120 seconds per conversion before a 504.
- Options this converter can't apply yet, such as
ConvertSpeakerNotes=Separate, return 400 "… is not supported yet for PPT files". - Encrypted .ppt files can't be drawn yet; they return 422 whatever

Where teams use it
Converting legacy decks for long-term records
A .ppt from the early 2000s needs software that can still read the binary format. A multi-page TIFF of its slides can be read by imaging tools without it, one frame per slide.
Attaching slides to cases in imaging systems
Where a system built for scanned documents pages through TIFF frames, send the deck at the resolution it expects and attach one file per presentation.
Questions
Why is one slide as TIFF bigger than the whole deck?
Single frames are written uncompressed. At 96 DPI one slide is 2,073,834 bytes, while the five-frame file is 225,807 bytes because multi-page TIFFs are LZW-compressed. Ask for two or more slides together when file size matters.
Which resolution should I choose for archiving?
Match what your archive expects. The slides are drawn from vector shapes, so a higher value adds real detail, at the cost of size: at 150 DPI the five frames take 375,523 bytes, at 96 they take 225,807.
Can the TIFF frames be grayscale?
Yes, both in a single-slide answer and in the multi-page file. With ColorSpace=gray at 96 DPI the five frames have one channel each, and the file takes 122,376 bytes against 225,807 in color.
