How to compress multiple images
Aero Tools currently compresses one image at a time — but with a fast in-browser engine, each image takes 1–3 seconds. To compress a batch: upload → compress → download → upload the next. No server roundtrip, no waiting for cloud upload. You can process 20–30 images in a few minutes.

Tips for bulk compression workflow
Set your target quality or file size once — the settings persist for each image you upload, so you only configure it at the start of the session.
Use the same output format (JPEG at 85%) for all images in a batch. This gives consistent results across your image library.
Use a browser with multiple tabs to parallelise: open the tool in 3–4 tabs and drag one image to each tab simultaneously for faster batch processing.
Frequently Asked Questions
Does this tool support drag-and-drop for multiple files at once?
Currently the tool processes one image per session. Drop one image, compress it, download, then drop the next. Multi-file drop support is planned for a future update. For now, the single-file workflow with fast browser compression is the most private and reliable approach.
What is the fastest way to compress many images?
Open Aero Tools in multiple browser tabs (3–4 tabs works well). Set the same compression settings in each tab. Drag one image to each tab and click Compress simultaneously. All tabs run independent compression in parallel on your device's CPU cores.
