Scanned Spanish invoices and forms are just images until you run OCR. With GekiPDF's ocr-pdf tool, Tesseract adds a searchable text layer so you can find any number or name in seconds. For Spanish documents, select the spa language pack and scan at 300 DPI — that's the sweet spot for accuracy on printed text.
Upload a file up to 50 MB, and GekiPDF processes it without signup or watermark. The OCR engine works best with clean scans; blurry or low-contrast pages will reduce recognition quality. Files are deleted after one hour, and you get 40 conversions per hour per IP — enough to handle a batch of receipts.
Frequently asked questions
What DPI should I use for Spanish OCR?
Use 200-300 DPI input for best accuracy. At 300 DPI, small print on invoices is readable by Tesseract. Lower than 150 DPI may miss characters.
Does GekiPDF support accents and ñ in Spanish?
Yes, the spa language pack includes accented characters like á, é, í, ó, ú and ñ. It recognizes them correctly when the scan is sharp and at 300 DPI.
How long does the OCR take?
Processing time depends on file size and page count. A typical 10-page invoice at 300 DPI takes under a minute. You can do up to 40 conversions per hour.
