Send Lossless Images

Send full-resolution images to the ChatGPT Mobile runtime without leaving the app or losing quality.

Large images attached directly in ChatGPT Mobile may reach the runtime with heavy compression. Fine text and small visual details can become difficult to inspect. Send Lossless Images provides a smooth upload flow for OCR, long screenshots, document review, design feedback, and image analysis.

This repository provides a standalone Skill prompt file. It uses Dropbox when the connector is already available. Each task receives an isolated upload folder and can accept multiple images. Uguu, TmpFiles, and Litterbox provide temporary upload choices when Dropbox cannot be used.

Use in ChatGPT Mobile

Open Work mode in the ChatGPT Mobile app and send this instruction:

Please open and read the following standalone prompt file, then follow its instructions for this task. Do not install it as a Skill or plugin:
https://raw.githubusercontent.com/Byte-Naut/send-lossless-images-skill/main/send-lossless-images-skill.md

ChatGPT will use the instructions in the current conversation. You can also download send-lossless-images-skill.md and attach it directly to the task.

What it provides

1. Full-resolution transfer for one or many images
2. A separate Dropbox upload space for each task
3. Tested temporary upload choices when Dropbox is unavailable
4. Original file retrieval for OCR and image processing
5. Cleanup confirmation after the task is complete
