When you need image-to-editable conversion

  • AI-generated slide images: many AI tools output beautiful PNG slides that have a typo or need your real numbers.
  • Lost source files: the original deck is gone and only screenshots from a meeting remain.
  • Quick edits to a design export: a designer sent a flattened image and you need to change a date before the meeting.

Why "OCR and paste" doesn't work well

OCR only recognizes characters. It doesn't handle position, font size, color, or the original text still sitting in the image. Paste the recognized words on top and the old text shows through beneath your edits; then you still have to align and style every block by hand.

A workable process is: detect text and its position → erase it from the image and fill the background → write back text boxes with matching position, size, and color → review. LingSlide automates the first three steps.

How to do it

  1. Get the sharpest original image you can (PNG or JPG, ideally 1600 px wide or more).
  2. Open the LingSlide app and drop in the image.
  3. Keep text reconstruction on. Optional 2× enhancement improves the processed background, not OCR accuracy. Use a clearer source image when possible.
  4. Review each text block against the original and click to edit.
  5. Download the PPTX and copy the slide into your presentation.
Several images? The free tier processes 1 file per day. Combine screenshots into one PDF first (macOS Preview, or "Print to PDF" on Windows), then upload up to 20 pages at once.

Getting better recognition

  • Screenshot instead of photographing the screen.
  • Use the original file, not a compressed copy from a messaging app.
  • Crop to the slide only — remove browser chrome, taskbars, and watermarks.
  • Double-check look-alike characters (0/O, 1/l) and every figure before presenting.

Frequently asked questions

What's the difference between inserting an image and converting it?

Inserting an image just places a picture on a slide; the words are still pixels. Converting it recognizes the text, removes it from the background, and adds editable text boxes on top, so you can change the wording while the design stays the same.

Which image formats are supported?

PNG and JPG/JPEG. Each image counts as one page. For several images, combine them into a single PDF and upload that (up to 20 pages).

How sharp does the screenshot need to be?

Aim for at least 1600 pixels wide with crisp text. Images forwarded through chat apps are often compressed; use the original when you can.

Can I use a phone photo of a screen?

You can try, but photos add perspective distortion, moiré, and glare, so results are noticeably worse than with a screenshot.
