Best for, limitations, and fit
Best for
- Website owners trying to improve page speed and upload reliability.
- Content teams compressing batches of screenshots and product images.
- Anyone with file-size limits on forms, email, or ad platforms.
Not best for
- Heavy artistic editing or creative retouching.
- Cases where original-size archival quality matters more than speed.
Limitations
- Very aggressive compression can soften details or create artifacts.
- Resizing changes dimensions, so it is not ideal for every print workflow.
- If a format change is the bigger issue, use a dedicated converter next.
Quality, privacy, and common mistakes
Quality tips
- Lower quality gradually instead of making one aggressive jump.
- Resize only when the destination actually needs smaller dimensions.
- Compare readability carefully if the image contains screenshots or text.
Common mistakes
- Compressing too hard without checking whether a simpler format change would help more.
- Resizing images that still need the original dimensions for another platform.
Privacy note
Compression is commonly used on unpublished assets, so local processing can remove friction for internal review and publishing teams.
