What SizeFix does
SizeFix provides focused tools for image compression and resizing, image format conversion, PDF compression and page management, PDF and Word conversion, QR code generation and scanning, images-to-PDF conversion and people-focused background removal.
How SizeFix is different
Each tool is built around a specific user outcome rather than a generic file-processing page. Where possible, SizeFix checks the result before presenting success. For example, image tools validate requested file-size or dimension requirements, PDF tools check generated documents, and background removal rejects implausible masks rather than offering a visibly damaged cut-out as a finished result.
How files are processed
Many SizeFix utilities process files directly in the browser. This reduces unnecessary file transfer and makes it possible to complete common tasks without sending every source file to a SizeFix application server. Some tools may load third-party browser libraries required for conversion or rendering, but the file-processing workflow is designed to remain client-side where practical.
Who SizeFix is for
The site is designed for everyday tasks such as meeting job-application upload limits, preparing passport or visa photos, reducing attachments for email, converting documents, combining phone photos into PDFs, preparing website images, creating QR codes for print, and fixing files rejected by online portals.
How guidance is written
SizeFix guides explain the problem behind the tool, including when to resize instead of compress, when JPG is more appropriate than PNG, what happens when a PDF target is physically unrealistic, and how to preserve readable text and faces while reducing file size. Guidance is reviewed alongside the actual tool behavior so instructions match what the site can do.
Accuracy and limitations
No file utility can guarantee that every third-party website will accept every output because external portals can change their rules. SizeFix therefore encourages users to check the destination site's current requirements and reports when a requested target cannot be achieved reliably instead of claiming success where the result does not meet the stated constraint.
