If you upload files, please note the following restrictions:

• must be .gmi, .txt, .png, .jpg, or .mp3 files
• must be 100,000 bytes or less

Remember that 100KiB is very small for images and audio files. If you’re uploading images, consider resizing them, stripping metadata, and lowering their quality. If you’re uploading MP3 files, use lower their quality, possibly using a “voice” preset or the like.

Image example: I have a JPG file, 1600×1067 pixels, 555KiB. Here’s how I create a new file that is 1000×667, 92KiB.
