Question 3

Are my files uploaded to your servers?

Accepted Answer

No. Compression, conversion, and photo tools are designed to process files in your browser whenever possible. Your PDFs, photos, and videos stay on your device — we do not store your file contents.

Question 4

Can I compress a PDF online for free?

Accepted Answer

Yes. The PDF compressor reduces file size while keeping text readable. Choose a mode, preview the result, and download — all in the browser, with daily free limits.

Question 5

How do I compress JPG, PNG, or WebP images?

Accepted Answer

Open the image compressor, drop your photo, and pick Smart, Extreme, or Low mode. You will see the size you saved before downloading. Processing stays on your device.

Question 6

Can I convert HEIC or WebP photos to JPG?

Accepted Answer

Yes. Convert iPhone HEIC photos to JPG or PNG, and convert WebP images to JPG or PNG with our free converters. Ideal when a form or email only accepts common formats.

Question 7

How do I compress MP4 video or extract MP3 audio?

Accepted Answer

Use the video compressor to shrink MP4 files for sharing, or convert MP4 to MP3 to extract audio. Both tools work in the browser with free daily limits.

Question 8

Can I compress a ZIP or convert between PDF and images?

Accepted Answer

Yes. Shrink ZIP archives with the ZIP compressor, turn PDF pages into JPG/PNG, or combine images into one PDF. Useful for email attachments and form uploads.

Question 9

How do I merge PDF files online?

Accepted Answer

Use Merge PDF to combine multiple PDFs into one file. Reorder pages if needed, then download the merged PDF. Processing is private and free within the daily limit.

Question 10

Can I split a PDF or extract pages?

Accepted Answer

Yes. Split PDF lets you extract a page range, split every N pages, or save each page as its own file. Handy when a portal only accepts a few pages.

Question 11

Is there a free background remover?

Accepted Answer

Yes. Remove an image background and download a transparent PNG or a clean white backdrop. Useful for product shots, signatures, and profile photos — no app install.

Question 12

Do you have tools for government exam photo uploads?

Accepted Answer

Yes. The government exam toolkit includes a passport-size photo maker, image dimension checker, photo + signature maker, document scanner, scan-to-PDF, and name/date stamp — sized for common form rules.

Question 13

How do I make a passport-size photo or check dimensions?

Accepted Answer

Use Passport Size Photo Maker to crop, set mm/inch size, DPI, and KB limits. Use Image Dimension Checker to verify width, height, DPI, and file size before you upload to a portal.

Question 14

Can I prepare a photo and signature together?

Accepted Answer

Yes. Photo + Signature Maker resizes both files with separate size and KB controls, then lets you download them separately or as a ZIP for exam forms.

Question 15

How do I scan a document or make a scanned PDF from photos?

Accepted Answer

Document Scanner cleans phone photos with contrast and crop filters. Scan to PDF turns one or more photos into a multi-page PDF — helpful for certificates and marksheets.

Question 16

Can I add a date or name stamp on a photo?

Accepted Answer

Yes. Add Date to Photo overlays a date, name, or custom text with position and style controls, then downloads JPG or PNG — often needed for form submissions.

Question 17

What is Bulk Product Photo Studio and Passport Photo Sheet Maker?

Accepted Answer

Bulk Product Photo Studio batch-edits seller photos (white background, square canvas, soft shadow, watermark, ZIP export). Passport Photo Sheet Maker layouts multiple copies on 4×6, 5×7, A4, or Letter for printing.

Question 18

Can I resize or create a digital signature online?

Accepted Answer

Yes. Signature Resizer matches pixel and KB limits for forms. Digital Signature Creator lets you draw, type, or upload a signature and download a clean PNG — including transparent options.

Question 19

Is AllFileCompressor safe for sensitive files?

Accepted Answer

It is built as a zero-upload, on-device toolkit whenever possible. Sensitive PDFs and ID photos are processed in your browser so they are not archived in our cloud storage.

Question 20

What is Pro for $3/month, and do I need to install anything?

Accepted Answer

Pro gives you unlimited access to all AllFileCompressor tools for just $3/month, with no daily usage limits. Compress, convert, resize, and use all available tools as much as you need. No software installation is required — everything works directly in your browser on desktop and mobile.
