Compress PNG for a smaller file size
PNG is lossless — shrinking usually means fewer pixels or smarter encoding for screenshots. Start by reducing the longest edge, then lower quality only after you switch to JPEG or WebP if the destination allows.
Resize Options
Upload images with drag & drop, choose from preset sizes or enter custom dimensions. High-quality output, instant preview, and free to use.
PNG-specific tactics
UI screenshots often have flat colors — resizing height/width beats cranking aggressive PNG quantization in the browser.
If you need postage-stamp sizes for forums, consider PNG→JPEG or PNG→WebP once transparency is irrelevant.
Keep transparency intentional
Do not flatten to JPEG when you still need alpha — export WebP instead if the site accepts it.
Crop dead borders from screenshots before compression; empty margins waste kilobytes.
Then host or embed
After download, upload to ImageUpload.app when you need a stable HTTPS URL for Notion, GitHub, or chat.
Developers can batch with the REST API when many assets ship together.
Resize your images to any size, maintain aspect ratio, adjust quality, and save in different formats. Ready-made sizes for social media profiles, cover photos, and other platforms.
