Save the chosen items by slide
Choose a .pptx file or drop it here. “Try a sample” builds a sample deck with pictures, an unused picture and an embedded workbook on your device.
In the list, check each picture’s look, size and file size, and the slide it is used on. Video and sound show their format and size.
Items that nothing in the deck uses are marked “Unused”.
Tick what you want and press “Save selected”. One item is saved in its own format; several are packed into one ZIP. To save a single item, press “Save” on its row.
File names show the slide, such as Slide3_image2.png, and a number is added when names repeat.
What it does
Shows the slides that use each item
Follows the relationships (rels) from slides, layouts and masters to each picture and shows the slides that use it. An item used on several slides is saved under the name of the first slide.
Lists video and sound too
Lists the MP4, MOV, WMV, AVI, MP3, WAV and M4A files in ppt/media with their format and size. Video and sound are saved as they are, not played.
Reads the format from the content
Identifies PNG, JPEG, GIF, BMP, WebP, TIFF, EMF, WMF and SVG from the first bytes, not the extension. Browsers cannot draw EMF, WMF or TIFF, so those get no thumbnail; they show the format and size and can still be saved.
Takes items out without changing the deck
Only reads the file; the .pptx is never rewritten. Each ZIP is built fresh when you save. Against ZIP bombs, every part is checked for its unpacked size and its expansion ratio before it is taken out.
Use cases
- Pull every photo and chart from a proposal at its original resolution in one go
- Take a video from a talk to reuse in another document
- Check that no unused picture is left in the deck before you distribute it
- Open the data behind an Excel chart embedded in a slide

Limits & notes
- Files up to 1 GB, up to 20,000 parts in a ZIP. A part is taken out only if it is up to 512 MB unpacked.
- A part that expands more than 1,000 times its compressed size is not taken out, because it may be a ZIP bomb (only parts over 1 MB are checked for this).
- The selected items together may be up to 1 GB. Previews are made for pictures up to 64 MB and 64 megapixels; large video is listed without a preview.
- It also works on phones, but for decks of several hundred MB with video a computer is recommended.
- Items used only in notes or masters are labelled with those places.
Privacy & safety
Reading, listing, previews and building the ZIP all happen in your browser. Neither the file’s contents nor its name is ever sent to or stored on a server.

Office Size Inspector
Find out what makes a Word, Excel or PowerPoint file heavy: a breakdown by images, video, fonts, embedded objects, XML and more, with every picture’s resolution compared with how large it is shown and where it is used. Then make a lighter copy while the original stays unchanged. Files are never uploaded.
Extract Anything
Open a file and get its text, images, tables, URLs / e-mail / phone numbers, QR codes and barcodes, attachments and metadata, each with a count and the place it came from (file, page, sheet). What could not be extracted is explained. OCR is not supported.
Image Compressor
Drop images to shrink them in bulk while keeping them sharp. Convert to WebP or AVIF, resize, and compare before and after. Your images are never uploaded.
Images to PDF
Drop images, put them in order and get one PDF. Choose page size, orientation and margins; phone photos are rotated correctly. Images are converted on your device and never uploaded.
Compress PDF
Drop a PDF to cut its size. Only photos and scans are recompressed, so text and graphics stay crisp. Your PDF is processed on your device and never uploaded.
PDF Editor
Lay text (Japanese included), shapes, arrows, a highlighter, freehand drawing and images on top of a PDF, and fill in its form fields. Text, shapes, highlights and freehand strokes are written as PDF vectors and real text, never as pictures; an added image is embedded as an image. Rewriting the original text and true redaction are not possible.
