JPG and WebP at a glance
| JPG | WebP | |
|---|---|---|
| Transparency | No; transparent areas become white | Yes |
| Compression | Lossy, small files for photos | Lossy or lossless, usually 25–35% smaller than JPG |
| Typical use | Photos, email attachments, uploads | Images on websites |
| Browser support | Every browser and app | All current browsers |
The browser decodes JPG directly. Converting does not restore detail that JPG compression already removed.
WebP keeps transparency. The quality slider runs from 10% to 100%; lower values make smaller files.
Are my images uploaded?
No. The JPG files are decoded and saved as WebP in your browser. They stay on your device.
Automate Your Screenshots. with Temposhot.
The tools on this page work on files you already have. Temposhot is the Mac app that makes those files: it captures a screen, window or area on a timer, presses a key between shots, and exports the set as PDF, images, ZIP or MP4.
Free download. Apple Silicon, macOS 14 or later.
Features
Hands-free capture
Set a stop condition and an interval once. Temposhot keeps capturing while you do something else.
How Auto Capture works- Stop after a number of screenshots, a duration, or at a clock time
- Intervals in milliseconds, seconds, minutes or hours
- A whole display, one app window, or a custom area
Page-by-page archives
Add a key press after each screenshot and the reader app turns its own pages.
Save pages as a PDF- Right Arrow, Page Down, Space or any recorded key combination
- The Kindle preset: 20 screenshots, 500 ms apart, Right Arrow after each
- Export the ordered pages as one searchable PDF
Step-by-step guides from clicks
Do the task once. Action Capture saves the screen before every click and marks where you clicked.
About Action Capture- One page per accepted click, in order
- Titles, descriptions, arrows, shapes and framing in the editor
- Export the guide as PDF, PNG, JPG, WebP or ZIP
Website batches
Paste a list of URLs and capture every page with its own viewport, wait and format settings.
