What can I do with audio?
Batch convert audio to MP3, WAV, M4A/AAC, FLAC, Ogg Vorbis or Opus. Trim and adjust a recording, join recordings in order, or split a recording into timed parts. Choose sample rate, mono/stereo, volume and fades. Download completed files individually or prepare a ZIP.
Why does audio take time to open?
The first audio operation downloads about 31 MB of processing software; recordings stay on your device. Use up to 20 files, 100 MB each and 250 MB combined. Recordings and joined output are limited to 30 minutes. Complex or large jobs may need a desktop browser with more memory. Cancel stops the worker.
Why does my audio sound different?
The timing preview is a lightweight mono copy without export effects. Listen to the exported file to check volume, fades, quality and channels. Lossy encoders may add delay or padding; use WAV for precise cuts. WAV and FLAC can be larger and cannot recover lost detail. Source tags, chapters and artwork are not copied. Ogg, Opus or FLAC playback varies by browser, even when conversion succeeds.
A PDF cannot be opened or merged
Password-protected PDFs, interactive forms and signature fields are not supported. Export an unencrypted, flattened copy from the original application and try again. PDF jobs allow up to 30 files and 100 MB total, with at most 500 pages. Complex documents may need smaller batches.
How do I split a PDF?
Choose one PDF in Split PDF, then enter pages such as 1-3, 5, 8. The output is one PDF in the order entered; repeated pages are included once. Use separate runs for separate output files. Open your download and check the pages before sharing it.
How are images placed in a PDF?
Images to PDF places one picture per page, in your chosen order, without stretching or cropping. Pictures are converted to JPG with a white background and limited to 4,096 pixels on the longest side. Choose A4, Letter or pages fitted to each image.
The result is above my KB target
The compressor lowers quality at the dimensions you selected. Some pictures cannot fit within a very small limit this way. Choose a smaller Image size, such as 1,280 or 800 pixels, and convert the original again. Use JPG, WebP or AVIF for target-size compression. Check the download before using it.
The converted image is larger than the original
A different format does not always produce a smaller file. PNG, BMP and TIFF can be much larger than a compressed photo. Try Image Compressor and compare the size shown beside each result. Keep PNG when preserving sharp graphics or transparent pixels matters more than file size.
A large image fails or the page closes
Try one file at a time and choose a smaller Image size before converting. Closing other tabs may free memory. Files may fit the displayed admission limits but still exceed a device’s decoding capacity. If necessary, use a device with more available memory. Refreshing clears the queue, so save completed results first.
I cannot find my download
Use Save beside a completed result, or Download all images as ZIP below the file list. Check the browser’s downloads list and its selected download folder. On an iPhone or iPad, also check Downloads in the Files app. If an image opens in a tab, use your browser’s save or share action. Open a ZIP file to extract its images before uploading them elsewhere.
An SVG or HEIC file is rejected
SVG must be a self-contained static drawing. External references, embedded content, scripts and unsupported SVG elements are rejected. HEIC and HEIF have multiple variants, and some cannot be decoded. Make sure the original file is available on the device and is not a cloud placeholder. Renaming a file extension does not change its actual format.
My animation, metadata or print colors changed
These tools export still images. Animation becomes one frame, and TIFF exports one selected page. Source EXIF, GPS, DPI and color profiles are not copied. This version is intended for screen images, not color-critical print work or archival preservation. Keep your original.
