Before you upload
Should I use JPG, PNG or WebP?
JPG is usually efficient for photos, PNG is useful for graphics and transparency, and WebP can provide smaller modern-web files. SizeFix lets you convert between these formats.
What if the platform also has a file-size limit?
Use the maximum-KB field on SizeFix resize pages, or open a dedicated image compression target such as 300KB.
Will resizing stretch my image?
Exact aspect-ratio presets crop before resizing rather than stretching the source.
Need a different image size?
Open the full image toolkit for exact dimensions, compression targets and format conversion.
