Frequently Asked Questions
What is the correct image size for a LinkedIn post?
LinkedIn recommends a 1.91:1 aspect ratio (1200×628 px) for single-image posts. Our "LI Post" preset automatically crops your image to this ratio, ensuring it displays without cropping or letterboxing in the feed.
What dimensions does a LinkedIn banner require?
LinkedIn profile banners use a 4:1 ratio (1584×396 px). Our "LI Banner" preset enforces this exact aspect ratio. Export as JPEG at 85–90% quality to stay well under LinkedIn's 8 MB upload limit.
Can I batch-resize multiple LinkedIn images at once?
Yes. Upload up to 10 images, apply the same crop ratio and quality settings to all via the "Apply to all" toggle, then download the full set as a ZIP. Every image is processed locally in your browser — no server upload, no queue.
Should I use WebP or JPEG for LinkedIn images?
LinkedIn accepts both formats but internally re-encodes uploads to JPEG. Export as JPEG at 85–90% quality for predictable output, or export as WebP to keep a smaller master file for your own archive before uploading.
Does this tool store my images or require an account?
No. All processing happens locally in your browser via the HTML5 Canvas API. No image ever leaves your device, no account is required, and the tool is completely free.
