Technical reference for how Filvo processes files, what stays on-device, and the current limits on AI jobs, downloads, and formats.
How processing works
Filvo has two processing modes. Do not collapse them into “everything stays on the device” or “everything is uploaded.”
| Mode | What happens | Tools |
|---|---|---|
| On-device | The file is processed in the browser (Canvas / PDF.js / pdf-lib). It is not uploaded to Filvo servers for the core effect. | Compressor, converter, editor, color picker, all PDF tools |
| API-processed | The file is sent through Filvo’s API to an AI provider only to generate the result. There is no public gallery and no personal photo library. | Image Upscaler, Background Remover, Object Removal |
Downloads never include a Filvo watermark. An account is optional — browser tools work without sign-in. See the Privacy Policy for how accounts, analytics, and cookies are handled.
Browser tools
These tools are unlimited. They run locally, so speed depends on the device and the file size — not a remote queue.
- Image Compressor — JPG, PNG, WEBP, AVIF — re-encoded with HTML5 Canvas. Metadata is stripped.
- Convert Image — PNG, JPEG, WEBP, GIF — format change stays on the device.
- Image Editor — Resize, crop, layers, watermarks, adjustments. Export PNG, JPG, or WebP.
- Image Color Picker — Sample HEX, RGB, and HSL from any image. Nothing is uploaded.
- Compress PDF — One unlocked PDF, up to 40 MB. Strong / Balanced / High.
- Merge PDF — Up to 25 unlocked PDFs, 40 MB each, 120 MB total. Pages copied as-is.
- Split PDF — Extract pages into one PDF, or a ZIP of one file per page. 40 MB.
- PDF Converter — PDF ↔ JPG / PNG / WEBP, or images into one PDF. 40 MB, or 25 images.
- Organize PDF — Rotate and reorder pages in one unlocked PDF, up to 40 MB and 80 pages.
AI tools
Background removal, upscaling, and object removal go through Filvo’s API so cutout, super-resolution, and erase quality stay high. The request exists to finish the job, not to store a gallery.
- Background Remover — transparent PNG cutout. Free download is a web preview (long edge 384px). Credits keep the original HD file.
- Image Upscaler — 2× / 4× / 8× super-resolution, not a canvas stretch. Upload JPG, PNG, or WEBP up to 20 MB. Free 2× download is a compressed WebP (JPEG fallback) up to 1,280px. 8× spends 4 credits.
- Object Removal — describe the object or paint a mask. Sign in for 2 credits. Free download is a web preview (long edge 384px). Credits keep the full-resolution file.
- Batch: Free keeps 1 image in the studio at a time. A credit pack can queue up to 25.
Credits & limits

Daily previews reset at midnight UTC. Browser tools, including every PDF tool, stay unlimited on every plan. Credits pay for AI jobs, not for merge or compress.
