Why HMRC forms reject your uploads
HMRC portals like Self Assessment, VAT returns, and Corporation Tax submissions have strict file size limits. A single high-resolution photo from a modern smartphone can easily exceed 5MB or even 10MB, causing the upload portal to immediately reject your evidence.
Instead of trying to manually crop or edit your photos and risking the loss of important details, compressing them to under 2MB ensures they pass HMRC's validation checks instantly. The compression is tuned to preserve the legibility of text and numbers, which is critical for receipts, invoices, and official documents.
Because tax documents are highly sensitive, it's risky to use random online compressors that upload your files to external servers. This tool processes everything locally in your web browser. Your financial documents never leave your device, ensuring complete privacy and compliance.

Frequently asked questions
What file size does HMRC accept?
HMRC typically accepts files up to 5MB per document, but some portals and forms have lower limits. Our tool compresses to under 2MB to ensure compatibility with all HMRC upload portals, including Self Assessment, VAT returns, and Corporation Tax.
Can I compress photos of receipts?
Yes! Take photos of receipts with your phone, then drop them here to compress. The quality is maintained well enough for HMRC's requirements — text remains legible while file sizes are significantly reduced.
Is this secure for tax documents?
Your documents never leave your device. All processing happens in your browser — no files are uploaded to any server. This is the most secure and private way to compress documents for HMRC.
What formats can I compress?
We support JPEG, PNG, WebP, GIF, and BMP images. These cover photos taken on phones, scanned documents, and screenshots. If you have PDF documents, you'll need to convert them to images first or use a dedicated PDF compressor.
