Browser-native utilities for image, PDF, SEO, and developer workflows. Supported workflows process selected file contents locally in your browser.
This page is the indexed directory for ConvertUnlimited's browser tools. Use it to choose an image, PDF, developer, data, or SEO utility without searching through generated landing pages.
Pick the tool that matches the job, complete the workflow in that browser tab, and review how local processing works if you need the technical boundary before choosing a tool.

Most visits here map to a few jobs: converting a format, shrinking a file, cleaning metadata, or working with PDF pages. The table routes each job to a tool, its output, and the limit worth knowing before a large batch.
| Task | Tool | Output | Known limits |
|---|---|---|---|
| Convert between PNG, JPG, and WebP | Image Converter | New image file in the chosen format | Batch speed depends on device memory. |
| Remove a flat-color or edge-touching background | Background Remover (Simple mode) | Transparent PNG | One image at a time; best on a single-color background. |
| Remove a complex or busy background | Background Remover (AI mode) | Transparent PNG | Downloads a segmentation model from a CDN on first use, so it needs a network connection at least once. |
| Reduce photo file size before upload or email | Image Compressor | Re-encoded JPG, PNG, or WebP | PNG re-compression saves less than JPG or WebP. |
| Resize images to fixed dimensions | Image Resizer | Resized image, same format | Upscaling past the source resolution adds no real detail. |
| Strip EXIF, GPS, or camera data from photos | Metadata Remover | Re-encoded JPG, PNG, or WebP with metadata dropped by canvas re-encoding | The metadata preview only reads JPEG EXIF; PNG and WebP still get stripped even though the preview shows nothing for them. Visible pixels are not touched. |
| Convert iPhone HEIC photos to a shareable format | HEIC to JPG | JPG or WebP files, optionally as a ZIP | Multi-image HEIC files such as Live Photos are not unpacked into separate images. |
| Add a text watermark to a photo | Watermark Tool | PNG, regardless of the source format | One image at a time, no batch or ZIP export, text only. |
| Convert images to AVIF | AVIF Converter | AVIF file(s), optionally as a ZIP | Depends on the browser's own Canvas AVIF encoder; unsupported browsers fall back to a message. |
| Combine photos into one PDF | Images to PDF | Single PDF file | Large photo sets increase in-memory size before saving. |
| Extract PDF pages as image files | PDF to Images | PNG or JPG per page, optionally as a ZIP | Higher render scale means sharper images at higher memory cost. |
| Combine multiple PDFs into one file | Merge PDF | Single merged PDF | Source PDFs load into memory in full; password-protected PDFs are not supported. |
| Pull specific pages out of a PDF | Split PDF | New PDF file(s) for the selected range, optionally as a ZIP | Same in-memory loading limit as Merge PDF. |
| Shrink a PDF's file size | Compress PDF | Restructured PDF | Rebuilds internal PDF structure; does not re-encode embedded images, so savings are modest on image-heavy files. |
| Generate a QR code for a URL or text | QR Generator | Static QR image | Static codes only, no dynamic or trackable option. |
| Preview a page's search or social card | Meta Preview Checker | Rendered preview from typed title and description | Manual input only; does not fetch a live URL's actual tags. |
| Format, clean, or convert JSON, CSV, or encoded text | Developer Tools (JSON Formatter, CSV Cleaner, CSV/JSON converters, Base64/URL encoders, UUID, Hash, Timestamp, Regex, Diff, JWT) | Formatted, converted, or generated text | Text-only; limited by the browser's text field, not a fixed file size. |
Every tool above runs from the browser's own APIs: FileReader or File objects read the selected file, a canvas or a client-side library (pdf-lib, PDF.js, jsPDF, JSZip, heic2any, or a segmentation model for AI background removal) transforms it, and canvas.toBlob or a library's save method produces a downloadable blob. There is no server-side job queue: a "batch" is a loop over files in the same tab, not a backend worker pool, so throughput is bounded by the device running it.
Each open file, decoded image, or loaded PDF byte array sits in the tab's memory while it processes, so very large files or batches can slow the tab or crash it, especially on phones and older laptops with less memory headroom than a desktop. Several tools also fetch a client-side library from a CDN on first use; that load needs a working connection, even though the selected file itself is not sent to a ConvertUnlimited server. Output support also depends on the browser: AVIF export only works where the browser's own Canvas encoder supports it. On mobile, expect a tighter memory ceiling and a background tab that can suspend mid-task; test with a small batch first for anything large.
