FAQ for 25 KB JPEG Compression
Common questions about 25 KB JPEG sizing.
25 KB is ideal for newsletter thumbnails, email previews, and lightweight marketing updates. It keeps inbox images small while still showing recognizable subjects, which helps emails load quickly and stay consistent across devices and clients.
25 KB gives a bit more clarity than 20 KB for edges and text, yet it is lighter than 30 KB for faster email loads. Use 25 KB when you need a clean preview but must keep the payload very small for campaigns and drip flows.
They can look sharp if the image is simple and uses bold shapes. Avoid tiny fonts and noisy backgrounds. If it looks soft, reduce dimensions slightly and test the preview inside your email template before sending to a test list or seed.
Often yes. A slight reduction in width is the easiest way to reach 25 KB without strong artifacts. Keep the aspect ratio locked so the preview stays aligned with the email layout and callouts in templates and modules.
Usually not. Full-width banners need more detail and a higher size budget. Use 25 KB for small preview cards or side images, and keep larger targets for primary hero banners and mastheads in campaigns and promotions.
If the file is already under 25 KB, the tool exports it unchanged to preserve quality. You can still crop or resize if you want a different framing, but no extra compression is forced for emails or newsletters and blasts.
Yes. Everything runs in your browser, so files are not uploaded or stored. This keeps campaign assets private and lets you iterate fast when you are preparing multiple email versions and segments for testing without server uploads.
