Left / top 0% → center 50% → right / bottom 100%. Automatic subject tracking is not supported.
Saves MP4. If the output exceeds your target, it tries up to three times at lower bitrates. Only files meeting the target are provided.
Drag on the image to add an area to hide, or enter its coordinates.
Use a solid fill to fully hide sensitive information. Blur and mosaic may allow the content to be guessed.
Reorder with ↑↓ in the file list. Image dimensions are kept and empty areas use the background color.
Multiple files are merged with original timestamps. Edit each cue's timing and text. VTT styles, positioning and comments are not preserved. UTF-8 files only.
Automatic captions · Beta
Multilingual models run on your device; audio is never uploaded. First use downloads a roughly 22 MB runtime and the selected model from Hugging Face. Korean, noise, music and names can be misrecognized: listen and correct the result.
Review and edit captions
Times are in seconds. Correct misrecognized words and delete unnecessary cues.
Use one audio segment or up to 10 video segments. Decimal seconds are supported. Leave the end blank for the rest of the file. Video clips are saved separately.
Fast cuts follow keyframe or audio-packet boundaries and may shift in position and duration. Accurate cuts use frame or sample boundaries. Re-encoding changes quality and uses more CPU.
Extract up to 10 images at original resolution, using the first decoded frame at or after each time. Color information and metadata may change.
Volume and fades require accurate processing. Volume above 100% may distort the sound.
The first video track is copied without re-encoding. Original audio, subtitles and chapters are removed. New audio starts at the beginning and is trimmed or silence-padded to match the video. Reinspect after changing files.
Images become PDF pages in list order. Only the first frame is used. Metadata and original compression are not preserved. Up to 20 images, 30 MB each, 100 MB total, 40 MP per image and 100 MP total.
Use the up/down buttons to reorder files. Enter per-file pages such as 1,3-5; leave blank for all pages. Output follows the specified order.
Page dimensions, text, images and vectors are copied. Document-level bookmarks, attachments, interactive forms and electronic signatures are not preserved. Encrypted PDFs are unsupported.
Guides & site information
Image formats and editing
Choose files and an output format. JPG suits photos; PNG and WebP support transparency. JPG and WebP are lossy; PNG metadata preservation is not guaranteed. Crop coordinates refer to original pixels. Review the before/after comparison.
Media processing and size estimates
Preserve mode copies codecs into compatible containers. Compatible conversion, accurate cuts and audio effects re-encode. Fast cuts may shift at keyframes or packets. Size estimates are approximate; content-dependent video, FLAC, images and documents have no reliable advance estimate.
HWP and PDF support
HWP 5.x and HWPX are supported. By default, missing original fonts block PDF conversion. HWP PDF output is a 192 dpi image PDF without searchable text. Existing PDF editing copies pages but does not preserve bookmarks, signatures, attachments or interactive forms. Image PDFs embed image pixels.
Privacy information
Selected files and connected fonts are processed on your device, without uploading them to a server. Settings, language and temporary work data are stored in the browser and can be removed by clearing site data. Conversion engines and automatic-caption models are downloaded. See the privacy and advertising/cookie pages for connection and cookie information about external services and the Coupang banner shown on South Korean connections.
Archive tools write large results to temporary storage on your device. Originals are never uploaded. Clear results or select new files to remove temporary outputs. Interrupted tabs may leave data; abandoned jobs older than a day are cleaned during subsequent use. Clear this Site’s browser storage to remove it immediately.
Troubleshooting and contact
For errors, privacy, and copyright inquiries, please send them to admin@infohubs.net. Provide the tool name, error message, and browser information, but exclude file names, file contents, and personal information.

Questions?
A few things to know before you start.
Can I convert HWP, Word and PDF documents?
Convert HWP 5.x/HWPX to PDF and between HWP/HWPX. Font checks, page previews and content-loss checks apply. PDF output is rasterized at 192 dpi, with no searchable/selectable text. Exact layout fidelity is not guaranteed. HWP conversion does not accept Word, DOCX or PDF input. Use PDF page editing to merge, extract, rotate or delete pages of existing PDFs.
Are settings or recent tool records saved?
Favorites, recently used tool IDs, language and explicitly saved settings are kept in this browser. Selected file contents and entered document text are not stored. Large archive results may remain in device temporary storage; clear results in the archive tool to remove them.
How do I convert a file?
Choose a task from All tools and add files. Review settings and limits, then start processing. Download completed files individually or as a ZIP.
Are there file size or count limits?
The main converter accepts up to 20 files / 200 MB total: images 30 MB, video 150 MB, audio 100 MB, documents 10 MB / 100 pages each. Separate archive, HEX, photo and PDF tools follow the limits shown on their own screens. Start with small jobs on a desktop for large files.
Do you support every media format?
Common formats are supported, but not every format. HEIC is input-only. AVIF needs browser decoding support. SVG can be rasterized; bitmap-to-vector conversion is not provided. Camera RAW, PSD, DRM and some special codecs are unsupported.
Can I crop and resize an image?
Choose Crop & resize. Drag an area or enter X/Y/width/height in original pixels. Enter both output dimensions for an exact canvas, or one to calculate the other proportionally. Keep aspect ratio adds transparent padding for PNG/WebP or the chosen background for JPG/BMP. Crops are individual per image. Upscaling does not restore detail.
Can I trim videos at specific times?
Choose Trim a video and enter decimal start/end seconds. Leave the end blank for the remainder. Fast cuts preserve codecs but may shift to keyframes. Accurate cuts re-encode at frame boundaries, consuming more CPU/battery and potentially changing quality. Originals are unchanged. The 150 MB limit applies to the full input regardless of cut length.
Why does video conversion take time?
Video is processed on your device. On first use, the engine is downloaded; its decompressed size is about 32 MB. Higher resolutions take longer; lowering resolution reduces work. Short clips are recommended on mobile.
Will my original file or quality change?
Original files are unchanged. Same format and default settings can return the original bytes. Media defaults to copying codecs when compatible. Opting into re-encoding may change quality and tracks. Image format changes may alter metadata, transparency, frames and colors. Review notices first. A lossless output cannot recover quality already lost.
