Step-by-step: compress Multiple Images at Once and Download a ZIP
- Step 1 — Keep a copy of the original file, verify the file type, and determine the result you need before changing anything.
- Step 2 — Open MediaExtractr’s Batch compress images tool and select your source file. Use the controls described on the tool page to choose the output you need.
- Step 3 — Process the file in your browser, save the resulting download and inspect the output using an app that supports the format.
What to check in the finished file
The goal is a usable result, not merely a file with a new extension. For this workflow, compress a whole set of photos at once and download them as a ZIP.. Pixels control actual image detail, while KB and MB describe file size. A DPI setting alone does not increase the number of pixels or rescue an overly small photo.
- Open the saved file and confirm it is complete and readable or playable.
- Compare the output with the original, especially text, dimensions, audio and page order where relevant.
- Check that the file meets the target app’s upload, compatibility or size requirements.
Common problem and how to avoid it
One quality setting may not suit photographs and screenshots equally. If the first result does not meet the requirement, return to the original and adjust the relevant settings rather than repeatedly converting an already degraded output.
