How Was This Data Collected?
All data comes from MiOffice's self-hosted Umami analytics instance — a privacy-focused, cookieless analytics platform. No personal data is collected. Sessions are anonymized and aggregated. File contents never leave the user's browser (100% client-side processing via WebAssembly), so no file data is available or analyzed.
The dataset covers February 1 to March 3, 2026 (30 days), representing 35,235 sessions, 70,830 pageviews, and 26,901 tool-use events across 76+ browser-based tools.
What File Types Do People Process Most Online?
According to MiOffice's 2026 File Processing Report, PDF operations account for 36% of all tool page views, making it the most-processed file type online. Image processing follows at 33%, with video at 17% and AI-powered tools at 11%.
| Category | Page Views | Share |
|---|---|---|
| PDF Tools | 23,234 | 36.2% |
| Image Tools | 21,081 | 32.9% |
| Video Tools | 10,565 | 16.5% |
| AI Tools | 7,127 | 11.1% |
| Scanner Tools | 626 | 1.0% |
| Other | 1,412 | 2.2% |
What Are the Most Popular Online File Processing Tools?
Image compression is the single most-used file processing tool, with 1,929 processing events in 30 days. PDF compression ranks second (1,710), followed by image resize (1,501). This reflects a universal need to reduce file sizes for email, web upload, and storage.
| Rank | Tool | Uses (30d) |
|---|---|---|
| 1 | Image Compress | 1,929 |
| 2 | PDF Compress | 1,710 |
| 3 | Image Resize | 1,501 |
| 4 | Image Convert | 1,008 |
| 5 | AI Background Removal | 867 |
| 6 | M4A to MP3 | 697 |
| 7 | AI Object Removal | 668 |
| 8 | PDF Split | 636 |
| 9 | PDF Merge | 611 |
| 10 | WebP to JPG | 602 |
| 11 | JPG to WebP | 564 |
| 12 | WebP to PNG | 556 |
| 13 | Video to MP3 | 507 |
| 14 | JPG to PDF | 501 |
| 15 | PDF to Word | 497 |
Which File Tools Generate the Most Downloads?
While image compression sees the most processing events, PDF Split generates the most file downloads at 7,830 in 30 days — nearly 4x the second-place tool. This is because PDF splitting produces multiple output files per operation (one per extracted page), inflating download counts relative to single-output tools.
| Tool | Downloads (30d) |
|---|---|
| PDF Split | 7,830 |
| PDF Unzip | 3,387 |
| JPG to WebP | 2,229 |
| Image Compress | 2,030 |
| HEIC to JPG | 1,633 |
| Image Convert | 1,343 |
| WebP to JPG | 1,302 |
| Image Resize | 1,217 |
| PDF Compress | 1,186 |
| PNG to WebP | 1,081 |
What Are the Most Common Image Format Conversions in 2026?
WebP conversion dominates image format changes. JPG to WebP (2,229 downloads) and WebP to JPG (1,302 downloads) are the top conversion pairs, reflecting the web industry's shift toward WebP while legacy systems still require JPG. HEIC to JPG conversion (1,633 downloads) remains strong as iPhone users convert Apple's proprietary format for broader compatibility.
Top “Convert To” Formats
- 1. WebP — 3,310 conversions (JPG→WebP + PNG→WebP)
- 2. JPG — 2,935 conversions (WebP→JPG + HEIC→JPG + AVIF→JPG)
- 3. PNG — 1,650 conversions (WebP→PNG + HEIC→PNG)
- 4. PDF — 1,443 conversions (JPG→PDF + image→PDF)
- 5. MP3 — 1,209 conversions (M4A→MP3 + video→MP3)
Legacy Format Observation
HEIC and AVIF — two modern formats — together account for 2,151 “convert away” events, almost entirely to JPG. Users adopt these formats via device cameras and CDN delivery but immediately convert them for email, social media, and legacy workflows that don't support newer codecs.

Why Asia Dominates
High mobile internet penetration combined with limited access to paid desktop software (Adobe, Microsoft Office) drives demand for free, browser-based alternatives. Privacy-first, zero-upload processing is especially valued in markets with slower upload speeds and data cost concerns.
What Devices Do People Use for Online File Processing?
File processing is no longer a desktop-only activity. 47% of all sessions come from mobile devices (phones + tablets), with laptop/desktop at 50% and tablets at 0.5%. Chrome dominates at 77% browser share, followed by iOS Safari (6.5%) and Edge (5.3%).
Device Split
- Laptop: 17,203 sessions (48.8%)
- Mobile: 16,515 sessions (46.9%)
- Desktop: 539 sessions (1.5%)
- Tablet: 165 sessions (0.5%)
Browser Share
- Chrome: 77.3%
- iOS Safari: 6.5%
- Edge: 5.3%
- Chrome iOS: 4.3%
- Firefox: 2.0%
- Opera: 1.0%
- Safari (macOS): 0.9%
How Popular Are AI-Powered File Processing Tools?
AI tools account for 11.1% of all tool page views — a significant share given that the category only contains a handful of tools versus 30+ in the PDF and image categories. Background removal (867 uses) and object removal (668 uses) are the standout AI tools, both powered by on-device ONNX Runtime inference with no server processing.
Privacy Implication
All AI inference runs locally in the browser via WebAssembly (ONNX Runtime). Models are downloaded once and cached in IndexedDB. No images are ever sent to a server — making these tools suitable for sensitive content like ID photos, medical images, and confidential documents.
How Do Users Find Online File Processing Tools?
Google organic search drives 76.5% of all sessions, followed by direct/internal navigation (24.6%), Bing (4.7%), and Yahoo (5.0% across all regional variants). DuckDuckGo brings 0.8%, indicating a small but measurable privacy-conscious user segment.
| Source | Sessions | Share |
|---|---|---|
| 26,977 | 76.5% | |
| Direct / Internal | 8,676 | 24.6% |
| Yahoo (all regions) | 2,116 | 6.0% |
| Bing | 1,648 | 4.7% |
| DuckDuckGo | 271 | 0.8% |
Do Users Return to Online File Tools?
Yes. 31% of sessions come from users who first visited 14+ days ago, and 59% from users who first visited 7-14 days ago. Only 1.5% of sessions are truly new users on any given day. The bounce rate is 59.3%, meaning 41% of visitors engage with at least two pages — well above industry average for utility tools.

Cross-country power users were identified in 15 countries — individuals returning 4-7 days out of 14, processing hundreds of files. The highest-volume power user generated 3,140 pageviews across 3 days from the United States, suggesting batch document processing workflows.
How Engaged Are Online File Processing Users?
Beyond file processing, MiOffice tracks anonymous engagement signals. In 30 days: 45,423 files were downloaded, 2,349 files were shared (via WhatsApp, Telegram, Gmail, X), and 2,581 file previews were opened. The share-to-download ratio of 5.2% suggests that approximately 1 in 20 processed files is shared directly from the tool.
