Fitbyte

Fitbyte is a responsive web tool for preparing images that must meet exact submission requirements. Upload up to 10 JPG, PNG, or WebP files and create up to three output specifications per image. You can keep original dimensions, resize by percentage, enter exact pixel dimensions, or set each image separately. Set maximum file size or a minimum-to-maximum KB range, preview the first result free, and download up to 30 JPEG outputs with a verification report in one ZIP for a one-time payment. There is no subscription. Fitbyte supports 11 languages and also includes a free browser-based signature background remover that creates transparent PNG files without uploading the signature to the server.

Students, job seekers, applicants, freelancers, and office workers preparing images for online forms, applications, portals, and document submissions.

Application and submission portals often require different pixel dimensions, formats, and minimum or maximum file sizes. Preparing several versions manually causes repeated trial and error, and users may not know whether the exported files actually meet every limit.
