Combine scanned pages, reports, or invoices into a single document for emailing or printing.

Open the Merge PDF tool from the homepage.

Upload two or more PDF files (order matters — rearrange if needed).

Click Process and wait for the merge to complete.

Download the combined PDF. The original uploads are deleted from our servers within about an hour.

For best results, use PDFs without password protection. Very large files may take longer on the free tier.

Our background remover uses AI to detect the subject and remove the backdrop automatically.

Go to Remove Background in the Image category.

Upload JPG, PNG, or WebP (clear subject works best).

Process the image and download a PNG with transparency.

Use good lighting and a contrasting background. Complex hair edges may need touch-up in a photo editor.

Large MP4/MOV files are hard to share. Compression lowers bitrate and resolution to shrink file size.

Open Compress Video under Video tools.

Upload your video and choose a quality preset (lower = smaller file).

Download the compressed output when ready.

Processing time depends on length and resolution. Pro users get priority queue and higher size limits.

Split a PDF when you need to share only part of a document, extract invoices from a batch export, or break a large report into chapters. It is faster than printing and re-scanning specific pages.

Our Split PDF tool reads the page structure of your document and lets you define ranges. You can extract a single page, a continuous range (e.g. pages 3–7), or split every page into its own file.

Open the Split PDF tool from the PDF category on the homepage.

Upload your PDF file — the tool shows a page count immediately.

Enter the page range you want to extract, or choose "Split all pages".

Click Process. Each range becomes a separate downloadable PDF.

Download your files. The originals are deleted from the server within one hour.

To extract every page as an individual file, use the "Split all" option.

Password-protected PDFs need to be unlocked before splitting.

For very large PDFs (100+ pages), processing may take a minute — do not close the tab.

Email services often cap attachments at 10–25 MB. Government portals and university submission systems may require even smaller files. Compressing a PDF removes redundant image data and embedded fonts to cut file size — sometimes by 70% or more.

The compressor targets embedded images (the biggest contributor to file size), duplicate font data, and metadata. Text content and layout are preserved so the document remains fully readable.

Go to Compress PDF in the PDF tools section.

Upload your PDF. A file size indicator confirms the upload.

Select a compression level: Screen (smallest), Ebook (balanced), or Printer (high quality).

Click Process and download the compressed file.

If the compressed file is still too large, try a lower quality setting.

PDFs that are already highly compressed (e.g. digital-native documents without images) may not shrink much.

Always keep the original — compression is lossy for embedded images.

Converting PDF to image is useful when you need a preview for a website, want to embed a page in a PowerPoint slide, or need to share a non-editable visual of a document. JPG is best for photos; PNG is better when you need transparency or sharp text.

Open the PDF to JPG (or PDF to PNG) tool from the homepage.

Upload your PDF.

Choose which pages to convert — all pages, or a specific range.

Select the output format (JPG or PNG) and image quality.

Process and download. Multi-page exports are packaged as a ZIP file.

Higher DPI (dots per inch) means sharper images but larger file sizes.

For web use, 96–150 DPI is usually enough.

For print or archival, use 300 DPI.

Different platforms require specific image dimensions. Profile pictures, banner images, product photos, and blog thumbnails all have different size requirements. Resizing before uploading also reduces bandwidth and speeds up page loads.

Resizing changes the canvas size while keeping all content — the image may stretch if the aspect ratio changes. Cropping cuts away parts of the image to fit a target ratio. Use resize when you need an exact pixel dimension; use crop when you want to trim content.

Open the Resize Image tool under Image tools.

Upload your JPG, PNG, or WebP image.

Enter the target width and/or height in pixels.

Toggle "Lock aspect ratio" to avoid distortion.

Click Process and download the resized image.

Facebook profile picture: 170 × 170 px

Twitter/X header: 1500 × 500 px

YouTube thumbnail: 1280 × 720 px

Instagram post: 1080 × 1080 px

JPG: Best for photos. Lossy compression gives small file sizes. No transparency support.

PNG: Lossless compression. Supports transparency (alpha channel). Larger files than JPG.

WebP: Modern format developed by Google. Smaller than JPG/PNG at similar quality. Widely supported in browsers.

AVIF: Newest format, even smaller than WebP but slower to encode. Good for static images on modern sites.

Open the Convert Image tool from the Image category.

Upload your source image.

Select the target format from the dropdown.

Adjust quality if applicable (JPG/WebP).

Download the converted image.

Upload multiple images at once to convert them all in a single operation. Files are returned as a ZIP archive.

Use the audio trimmer to cut a song clip for a ringtone, extract a quote from a podcast, remove silence at the start or end of a recording, or clip background music to fit a video.

The trimmer accepts MP3, WAV, OGG, FLAC, AAC, and M4A files. Output is in the same format as the input by default.

Open the Trim Audio tool under Audio tools.

Upload your audio file.

Set the start time and end time using the waveform preview or by typing timestamps.

Click Process to cut the segment.

Download the trimmed audio clip.

Zoom into the waveform for precise cuts around speech or beats.

For ringtones, keep clips under 30 seconds.

If you need to fade in/out, some audio editors let you apply fade after trimming.

Text-to-speech (TTS) technology converts written text into spoken audio. Modern AI-powered TTS produces natural-sounding voices that are hard to distinguish from human narration. Common uses include voiceovers for videos, audiobook production, accessibility for visually impaired users, and language learning.

Open the Text to Speech tool from the Audio category.

Type or paste your text into the input box.

Select a language and voice (male/female, speed).

Click Generate to create the audio.

Download the resulting MP3 file.

Break long texts into paragraphs for more natural pauses.

Add commas and periods to control pacing.

Use the slower speed setting for educational or accessibility content.

For multiple languages in one script, switch voice language for each section.

Speech-to-text (also called transcription) converts spoken audio into written text. It is useful for meeting notes, interview transcripts, subtitles, and accessibility captions. Our tool uses Azure AI Speech, which supports over 10 languages with high accuracy.

Open the Speech to Text tool.

Click the microphone button.

Allow microphone access when the browser prompts.

Start speaking — text appears in real time.

Click Stop when done, then copy or download the transcript.

Vietnamese, English, Japanese, Korean, Chinese, French, German, Spanish, Thai, Indonesian, Portuguese, and Russian.

Speak clearly and at a moderate pace.

Use a headset microphone for better audio quality.

Minimize background noise.

Pro users get unlimited session length; free users are capped at 2 minutes per session.

Trimming is the most common video edit. Use it to remove a long intro, cut out a mistake in a screen recording, extract a highlight from a longer clip, or shorten a clip for social media.

Open the Trim Video tool from the Video category.

Upload your video file.

Drag the start and end handles on the timeline, or enter exact timestamps.

Preview the selection if desired.

Click Process — the server cuts the video and returns just the selected segment.

Download the trimmed output.

When possible, the tool performs a lossless stream cut that is extremely fast and does not degrade quality. This works when the cut points align with keyframes. If you cut mid-frame, a short re-encode is applied automatically.

Trimming always reduces file size because you are keeping fewer seconds of video. If you need to reduce size further, run the result through Compress Video after trimming.

The ID photo maker crops and resizes your portrait to meet official document standards. It automatically removes the background and replaces it with a plain white or light-blue background as required by most passport and visa authorities.

Passport (ICAO standard): 35 × 45 mm

US Passport: 2 × 2 inches

Japanese residence card: 25 × 30 mm

Custom size: enter your own dimensions

Open the ID Photo tool under the Image category.

Upload a clear, front-facing portrait with good lighting.

Select the document type or enter custom dimensions.

The tool crops, resizes, and removes the background automatically.

Download the result as a JPG or PNG ready for printing.

Look directly at the camera with a neutral expression.

Use natural or evenly distributed lighting — avoid harsh shadows.

Remove glasses if the document authority requires it.

Ensure your full face and top of head are visible.

Watermarks identify document ownership, mark draft versions, label confidential files, or brand reports with a company name. Adding a watermark deters unauthorized copying and makes it clear if a document has been re-distributed.

Text watermark: type a word or phrase (e.g. "CONFIDENTIAL", your company name). You can choose font size, color, opacity, rotation, and position.

Image watermark: upload a logo PNG with transparency. The tool overlays it on each page at a specified size and position.

Open the Watermark PDF tool from the PDF category.

Upload your PDF.

Choose text or image watermark and configure the appearance.

Set opacity (30–50% is common for background watermarks).

Select which pages to apply it to (all pages, odd, even, or a range).

Process and download the watermarked PDF.

Use a diagonal orientation for draft watermarks — it is harder to crop out.

Keep opacity below 40% so the document content remains readable.

For branded PDFs, use your logo with white or light-colored text.
