Frequently Asked Questions

PixelLaunch is a free, browser-based image optimization tool. You can resize, compress, and convert images for social media platforms like YouTube, Instagram, Facebook, TikTok, LinkedIn, and more — without installing any software.

Yes, all tools on PixelLaunch are completely free. There are no watermarks, no hidden fees, and no sign-up required for most tools.

No account is needed to use most tools. Creating a free account lets you track your conversion history and removes the daily download limit.

PixelLaunch works on all modern browsers — Chrome, Firefox, Safari, and Edge. For the best experience, we recommend using the latest version of Chrome.

No. All image processing happens directly in your browser. Your files are never uploaded to or stored on our servers. Once you close or refresh the page, the images are gone.

Absolutely. Because processing is done client-side in your browser, we never have access to your images. We only collect minimal usage analytics to improve the service.

Yes. Since images are processed entirely in your browser and never leave your device, it is safe to use PixelLaunch for confidential documents or personal photos.

PixelLaunch supports JPEG, PNG, WebP, and GIF as input formats. Output can be saved as JPEG, PNG, or WebP depending on the tool.

The maximum upload size is 10 MB per image. For the Image to PDF tool, each individual image can be up to 20 MB.

Resizing to smaller dimensions can slightly reduce quality, but our tools use high-quality algorithms to minimize any visible loss. You can also adjust the quality slider in most tools to find the right balance between file size and quality.

Yes! Use the Custom Image Resizer tool to enter any width and height in pixels. You can also choose the output format and quality level.

We support YouTube, Instagram, Facebook, Pinterest, TikTok, Twitter/X, LinkedIn, and Twitch — with preset sizes for every image type on each platform.

Simply select your platform from the navigation or All Platforms page. Each tool shows the exact recommended dimensions, aspect ratio, and format for that image type.

We regularly review and update our dimension presets to match the latest guidelines from each platform. If you notice an outdated size, please let us know via the Contact page.

The Compress to KB tool uses a smart binary-search algorithm to repeatedly adjust the compression quality until your image is as close as possible to your target file size — for example, under 50 KB or 200 KB.

The tool gets very close to your target, typically within 1–5% of the specified size. Exact byte-level precision is not always possible due to how image compression algorithms work.

You can combine up to 10 images into a single PDF. You can also control the page size (A4, Letter, or fit-to-image) and orientation.
