Short version: open the free tool, drop your file, download the result. Nothing is uploaded.
Steps
- Open the WBS Image Compressor. This link opens it in Target size mode at 19 MB, a little under Discord's free 20 MB limit.
- Drop the image (or several) onto the page, or paste a screenshot.
- If you need it smaller (for a server emoji or sticker), type a new size in KB and press Re-run with these settings.
- Download the result and upload it to Discord as usual.
Discord's current limits (checked November 2026)
According to Discord's File Attachments FAQ, free accounts can upload files up to 20 MB (raised from 10 MB in August 2026). Nitro Basic allows 50 MB and Nitro up to 1 GB, and boosted servers raise the limit for everyone in that server. Discord now checks the size before any compression, on phones too, so the number you see is the one that counts. Discord sometimes tests different limits, so if yours looks different, go by what the app tells you.
| What you're uploading | Target to type |
|---|---|
| Image, free account | 19456 KB (19 MB), or use the Under 20 MB preset |
| Image, Nitro Basic | about 49000 KB |
| Custom emoji (must be under 256 KB) | 250 KB, plus Max width 128 px |
| Sticker (must be under 512 KB) | 500 KB, PNG or WebP output, Max width 320 px |
Keep it looking good
- Most images already fit. A phone photo is usually 2 to 6 MB. Files over 20 MB tend to be huge PNG screenshots, panoramas or camera exports. For those, choosing JPG or WebP under Format gives the biggest saving with little visible change.
- Screenshots with text stay sharpest as WebP at quality 80 or higher.
- Animated GIFs: the compressor only keeps the first frame, so it is not the right tool for animations. It's built for still images.
Why compress here instead of a random website?
Lots of "compress for Discord" sites upload your image to their server first. The WBS compressor runs entirely in your browser, so the picture never leaves your device until you post it yourself. It's free, with up to 20 images at a time; WBS Tools Pro ($7 once) removes the batch limit and adds a ZIP download.
