Conversions for every need and disability context
任何自动化工具都无法替代专家审核或完整的法规符合性（WCAG、EN 301 549）。 您仍可将文件（PDF、Office、纯文本等）转换为更易阅读、更适配辅助技术的格式——例如单页 HTML，字号更大、对比更强并带导航地标——并可针对视障或听障用户调整图像、音频与视频。
Document → readable HTML
生成独立页面：更大字号、可选高对比、跳转链接与标题提示随所选语言匹配，阿拉伯语从右到左排版，并净化标记（移除脚本，缺失的图片 alt 以空装饰性 alt 填补）——来源可为 PDF、Word、Excel、PowerPoint、OpenDocument、纯文本、Markdown、EPUB、HTML 或 CSV。
Open accessible HTML toolDocuments & searchable text
Turn PDFs into plain text for copy-paste and assistive tech, or run OCR when the file is a scan or phone photo of a page.
Privacy & lighter media
Review hidden metadata before sharing files, and trim heavy images so pages load faster — especially on mobile or slow connections.
Vision, contrast, reading
For low vision or eye strain: favour high-contrast outputs, avoid tiny details in images, and use readable HTML for long text.
Vision — conversions we’re adding towards
- Scanned PDF / image PDF → text + HTML (OCR + heading / list detection): a baseline that assistive tech can navigate.
- PDF → single-column / text-first layout (simplified typography): lowers cognitive load and layout traps.
- Text in images → OCR to TXT, DOCX, HTML: foundation for further accessible formats.
- (Advanced) Simulate colour vision or strengthen separability with the dedicated image tool — pair with invert/grayscale filters for safer chart/UI palettes.
Hearing & clear audio
Loudness normalisation (EBU R128), mono audio, or burned-in subtitles for video.
- Loudness normalise (audio / podcast)
- Mono audio
- Burn subtitles into video
- Audio transcription (TXT, SRT, WebVTT)
- Video transcription (TXT, SRT, WebVTT)
- Voice cleanup — clearer speech (audio)
Hearing — conversions we’re adding towards
- Noise reduction + clearer speech, in line with loudness normalisation.
- Peak / loudness limiting for hyperacusis-sensitive listening (careful gain staging): complementing mono and loudnorm.
Motor precision & cognitive load
Fewer steps: save presets in the uploader, use QR to transfer without long typing, and batch files when possible.
In the uploader
Before you publish or share
- Put essential information in real text, not only inside images or scans.
- Check contrast on diagrams and UI mockups (invert, grayscale, colour-blind preview).
- For speech-heavy video, add subtitles or a transcript when you can.
Guides & best practices
Articles on compression, formats, subtitles, and publishing — a good complement to these tools.

Results depend on source files. Automated conversion may change layout. For regulatory audits, involve a specialist.
